urtwn driver fixes - missing include, free node references, shut down xfers first * include opt_wlan.h like a good little wlan driver; * add a function to free the mbufq /and/ the node references on it, or we will leak said node references; * free the mbufq upon NIC shutdown otherwise we may end up with a full list that we never begin transmit work on, and thus never drain it; * .. which frees it upon NIC detach too; * ensure urtwn_start() gets called after the completion of frame TX even if the pending queue is empty, otherwise transmit will stall. It's highly unlikely that the usb tx queue would be empty whilst the incoming send queue is full, but hey, who knows. This passes some iperf testing with and without the NIC being actively removed during said active iperf test. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; STA mode

[urtwn] first cut of getting the fast-frames / amsdu support in shape. The urtwn hardware transmits FF/A-MSDU just fine - it takes an 802.11 frame and will dutifully send the thing. So: * bump RX queue up from 1. Why's it 1? That's really silly. * Add the "software A-MSDU" encap capability bit. * bump the TX buffer size up so we can at least send A-MSDU frames. * track active frames submitted to the NIC - we can't make assumptions about how many are in flight in the NIC though. For 88E parts we could use per-packet TX indication, but for R92 parts we can't. So, just fake it somewhat. * Kick the transmit queue when we finish reception; try to avoid stalls. * Kick the FF queue a little more regularly. A-MSDU TX won't happen until the net80211 side is done, but atheros fast-frames support should now work. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; A-MSDU transmit.

[urtwn] migrate urtwn out into sys/dev/urtwn/ . There's some upcoming work to add new chipset support here and I'd like to only add 802.11n support to one driver, instead of both urtwn and rtwn. There's also missing support for things like 802.11n, some powersave work, bluetooth integration/coexistence, etc, and also newer parts (like 8192EU, maybe some 11ac parts, not sure yet.) So, this is hopefully the first step in a longer set of steps to unify rtwn/urtwn and extend it with more interesting chipset and functionality support. Reviewed by: kevlo

I /hope/ that nchains == nstreams here. * Add 11n channels in the call to ieee80211_init_channels(). * Don't enable HT40 for now - I'll have to verify the channel set command and tidy it up a bit first. * Teach the RX path about M_AMPDU for 11n nodes. Kinda wonder why we aren't just doing this in net80211 already, this is the fourth driver I've had to do this to. * Teach rate2ridx() about MCS rates and what hardware rates to use. * Teach the urtwn_tx_data() routine about MCS/11ng transmission. It doesn't know about short-gi and 40MHz modes yet; that'll come later. * For 8192CU firmware, teach the rate table code about MCS rates. * Ensure that the fixed rate transmit sets the right transmit flag so the firmware obeys the driver transmit path. * Set the default transmit rate to MCS4 if no rate control is available. * Add HT protection (RTS-CTS exchange) support. * Add appropriate XXX TODO entries.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

[urtwn] welcome basic 11n support to urtwn. This is a pretty good reference for teaching an almost-11n-capable driver about 11n. It enables HT20 operation, A-MPDU/A-MSDU RX, but no aggregate support for transmit. That'll come later. This means that receive throughput should be higher, but transmit throughput won't have changed much. * Disable bgscan - for now, bgscan will interfere with AMPDU TX/RX, so until we correctly handle it in software driven scans, disable. * Add null 11n methods for channel width / ampdu_enable. the firmware can apparently handle ampdu tx (and hopefully block-ack handling and retransmission) so I'll go review the linux code and figure it out. * Set the number of tx/rx streams. I /hope/ that nchains == nstreams here. * Add 11n channels in the call to ieee80211_init_channels(). * Don't enable HT40 for now - I'll have to verify the channel set command and tidy it up a bit first. * Teach the RX path about M_AMPDU for 11n nodes. Kinda wonder why we aren't just doing this in net80211 already, this is the fourth driver I've had to do this to. * Teach rate2ridx() about MCS rates and what hardware rates to use. * Teach the urtwn_tx_data() routine about MCS/11ng transmission. It doesn't know about short-gi and 40MHz modes yet; that'll come later. * For 8192CU firmware, teach the rate table code about MCS rates. * Ensure that the fixed rate transmit sets the right transmit flag so the firmware obeys the driver transmit path. * Set the default transmit rate to MCS4 if no rate control is available. * Add HT protection (RTS-CTS exchange) support. * Add appropriate XXX TODO entries. TODO: * 40MHz, short-gi, etc - channel tuning, TX, RX; * teach urtwn_tx_raw() about (more) 11n stuff; * A-MPDU TX would be nice! Thanks to Andriy (avos@) for reviewing the code and testing it on IRC.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

I /hope/ that nchains == nstreams here. * Add 11n channels in the call to ieee80211_init_channels(). * Don't enable HT40 for now - I'll have to verify the channel set command and tidy it up a bit first. * Teach the RX path about M_AMPDU for 11n nodes. Kinda wonder why we aren't just doing this in net80211 already, this is the fourth driver I've had to do this to. * Teach rate2ridx() about MCS rates and what hardware rates to use. * Teach the urtwn_tx_data() routine about MCS/11ng transmission. It doesn't know about short-gi and 40MHz modes yet; that'll come later. * For 8192CU firmware, teach the rate table code about MCS rates. * Ensure that the fixed rate transmit sets the right transmit flag so the firmware obeys the driver transmit path. * Set the default transmit rate to MCS4 if no rate control is available. * Add HT protection (RTS-CTS exchange) support. * Add appropriate XXX TODO entries.

[urtwn] first cut of getting the fast-frames / amsdu support in shape. The urtwn hardware transmits FF/A-MSDU just fine - it takes an 802.11 frame and will dutifully send the thing. So: * bump RX queue up from 1. Why's it 1? That's really silly. * Add the "software A-MSDU" encap capability bit. * bump the TX buffer size up so we can at least send A-MSDU frames. * track active frames submitted to the NIC - we can't make assumptions about how many are in flight in the NIC though. For 88E parts we could use per-packet TX indication, but for R92 parts we can't. So, just fake it somewhat. * Kick the transmit queue when we finish reception; try to avoid stalls. * Kick the FF queue a little more regularly. A-MSDU TX won't happen until the net80211 side is done, but atheros fast-frames support should now work. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; A-MSDU transmit.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

urtwn driver fixes - missing include, free node references, shut down xfers first * include opt_wlan.h like a good little wlan driver; * add a function to free the mbufq /and/ the node references on it, or we will leak said node references; * free the mbufq upon NIC shutdown otherwise we may end up with a full list that we never begin transmit work on, and thus never drain it; * .. which frees it upon NIC detach too; * ensure urtwn_start() gets called after the completion of frame TX even if the pending queue is empty, otherwise transmit will stall. It's highly unlikely that the usb tx queue would be empty whilst the incoming send queue is full, but hey, who knows. This passes some iperf testing with and without the NIC being actively removed during said active iperf test. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; STA mode

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

[urtwn] first cut of getting the fast-frames / amsdu support in shape. The urtwn hardware transmits FF/A-MSDU just fine - it takes an 802.11 frame and will dutifully send the thing. So: * bump RX queue up from 1. Why's it 1? That's really silly. * Add the "software A-MSDU" encap capability bit. * bump the TX buffer size up so we can at least send A-MSDU frames. * track active frames submitted to the NIC - we can't make assumptions about how many are in flight in the NIC though. For 88E parts we could use per-packet TX indication, but for R92 parts we can't. So, just fake it somewhat. * Kick the transmit queue when we finish reception; try to avoid stalls. * Kick the FF queue a little more regularly. A-MSDU TX won't happen until the net80211 side is done, but atheros fast-frames support should now work. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; A-MSDU transmit.

[urtwn] welcome basic 11n support to urtwn. This is a pretty good reference for teaching an almost-11n-capable driver about 11n. It enables HT20 operation, A-MPDU/A-MSDU RX, but no aggregate support for transmit. That'll come later. This means that receive throughput should be higher, but transmit throughput won't have changed much. * Disable bgscan - for now, bgscan will interfere with AMPDU TX/RX, so until we correctly handle it in software driven scans, disable. * Add null 11n methods for channel width / ampdu_enable. the firmware can apparently handle ampdu tx (and hopefully block-ack handling and retransmission) so I'll go review the linux code and figure it out. * Set the number of tx/rx streams. I /hope/ that nchains == nstreams here. * Add 11n channels in the call to ieee80211_init_channels(). * Don't enable HT40 for now - I'll have to verify the channel set command and tidy it up a bit first. * Teach the RX path about M_AMPDU for 11n nodes. Kinda wonder why we aren't just doing this in net80211 already, this is the fourth driver I've had to do this to. * Teach rate2ridx() about MCS rates and what hardware rates to use. * Teach the urtwn_tx_data() routine about MCS/11ng transmission. It doesn't know about short-gi and 40MHz modes yet; that'll come later. * For 8192CU firmware, teach the rate table code about MCS rates. * Ensure that the fixed rate transmit sets the right transmit flag so the firmware obeys the driver transmit path. * Set the default transmit rate to MCS4 if no rate control is available. * Add HT protection (RTS-CTS exchange) support. * Add appropriate XXX TODO entries. TODO: * 40MHz, short-gi, etc - channel tuning, TX, RX; * teach urtwn_tx_raw() about (more) 11n stuff; * A-MPDU TX would be nice! Thanks to Andriy (avos@) for reviewing the code and testing it on IRC.

[urtwn] use/track the last good RSSI for a given node, rather than no RSSI. Now that we're decap'ing A-MPDU frame, the firmware is only giving us PHY status information for the whole PPDU, rather than duplicatig it per frame. So, we fake it by maintaining the RSSI that we saw in the node struct and reuse it. This prevents us from getting some pretty garbage looking default RSSI values, which shows up as RSSI values of like "3" or "4" when doing active traffic. Tested: * RTL8188EU, STA mode

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl.

[urtwn] first cut of getting the fast-frames / amsdu support in shape. The urtwn hardware transmits FF/A-MSDU just fine - it takes an 802.11 frame and will dutifully send the thing. So: * bump RX queue up from 1. Why's it 1? That's really silly. * Add the "software A-MSDU" encap capability bit. * bump the TX buffer size up so we can at least send A-MSDU frames. * track active frames submitted to the NIC - we can't make assumptions about how many are in flight in the NIC though. For 88E parts we could use per-packet TX indication, but for R92 parts we can't. So, just fake it somewhat. * Kick the transmit queue when we finish reception; try to avoid stalls. * Kick the FF queue a little more regularly.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

[urtwn] welcome basic 11n support to urtwn. This is a pretty good reference for teaching an almost-11n-capable driver about 11n. It enables HT20 operation, A-MPDU/A-MSDU RX, but no aggregate support for transmit. That'll come later. This means that receive throughput should be higher, but transmit throughput won't have changed much. * Disable bgscan - for now, bgscan will interfere with AMPDU TX/RX, so until we correctly handle it in software driven scans, disable. * Add null 11n methods for channel width / ampdu_enable. the firmware can apparently handle ampdu tx (and hopefully block-ack handling and retransmission) so I'll go review the linux code and figure it out. * Set the number of tx/rx streams. I /hope/ that nchains == nstreams here. * Add 11n channels in the call to ieee80211_init_channels(). * Don't enable HT40 for now - I'll have to verify the channel set command and tidy it up a bit first. * Teach the RX path about M_AMPDU for 11n nodes.

[urtwn] welcome basic 11n support to urtwn. This is a pretty good reference for teaching an almost-11n-capable driver about 11n. It enables HT20 operation, A-MPDU/A-MSDU RX, but no aggregate support for transmit. That'll come later. This means that receive throughput should be higher, but transmit throughput won't have changed much. * Disable bgscan - for now, bgscan will interfere with AMPDU TX/RX, so until we correctly handle it in software driven scans, disable. * Add null 11n methods for channel width / ampdu_enable. the firmware can apparently handle ampdu tx (and hopefully block-ack handling and retransmission) so I'll go review the linux code and figure it out. * Set the number of tx/rx streams. I /hope/ that nchains == nstreams here. * Add 11n channels in the call to ieee80211_init_channels(). * Don't enable HT40 for now - I'll have to verify the channel set command and tidy it up a bit first. * Teach the RX path about M_AMPDU for 11n nodes. Kinda wonder why we aren't just doing this in net80211 already, this is the fourth driver I've had to do this to. * Teach rate2ridx() about MCS rates and what hardware rates to use. * Teach the urtwn_tx_data() routine about MCS/11ng transmission. It doesn't know about short-gi and 40MHz modes yet; that'll come later. * For 8192CU firmware, teach the rate table code about MCS rates. * Ensure that the fixed rate transmit sets the right transmit flag so the firmware obeys the driver transmit path. * Set the default transmit rate to MCS4 if no rate control is available. * Add HT protection (RTS-CTS exchange) support. * Add appropriate XXX TODO entries. TODO: * 40MHz, short-gi, etc - channel tuning, TX, RX; * teach urtwn_tx_raw() about (more) 11n stuff; * A-MPDU TX would be nice! Thanks to Andriy (avos@) for reviewing the code and testing it on IRC.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

[urtwn] welcome basic 11n support to urtwn. This is a pretty good reference for teaching an almost-11n-capable driver about 11n. It enables HT20 operation, A-MPDU/A-MSDU RX, but no aggregate support for transmit. That'll come later. This means that receive throughput should be higher, but transmit throughput won't have changed much. * Disable bgscan - for now, bgscan will interfere with AMPDU TX/RX, so until we correctly handle it in software driven scans, disable. * Add null 11n methods for channel width / ampdu_enable. the firmware can apparently handle ampdu tx (and hopefully block-ack handling and retransmission) so I'll go review the linux code and figure it out. * Set the number of tx/rx streams. I /hope/ that nchains == nstreams here. * Add 11n channels in the call to ieee80211_init_channels(). * Don't enable HT40 for now - I'll have to verify the channel set command and tidy it up a bit first. * Teach the RX path about M_AMPDU for 11n nodes. Kinda wonder why we aren't just doing this in net80211 already, this is the fourth driver I've had to do this to. * Teach rate2ridx() about MCS rates and what hardware rates to use. * Teach the urtwn_tx_data() routine about MCS/11ng transmission. It doesn't know about short-gi and 40MHz modes yet; that'll come later. * For 8192CU firmware, teach the rate table code about MCS rates. * Ensure that the fixed rate transmit sets the right transmit flag so the firmware obeys the driver transmit path. * Set the default transmit rate to MCS4 if no rate control is available. * Add HT protection (RTS-CTS exchange) support. * Add appropriate XXX TODO entries. TODO: * 40MHz, short-gi, etc - channel tuning, TX, RX; * teach urtwn_tx_raw() about (more) 11n stuff; * A-MPDU TX would be nice! Thanks to Andriy (avos@) for reviewing the code and testing it on IRC.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

It doesn't know about short-gi and 40MHz modes yet; that'll come later. * For 8192CU firmware, teach the rate table code about MCS rates. * Ensure that the fixed rate transmit sets the right transmit flag so the firmware obeys the driver transmit path. * Set the default transmit rate to MCS4 if no rate control is available. * Add HT protection (RTS-CTS exchange) support. * Add appropriate XXX TODO entries.

Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED. The origin of WEP comes from IEEE Std 802.11-1997 where it defines whether the frame body of MAC frame has been encrypted using WEP algorithm or not. IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates whether the frame is protected by a cryptographic encapsulation algorithm. Reviewed by: adrian, rpaulo

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl.

[urtwn] first cut of getting the fast-frames / amsdu support in shape. The urtwn hardware transmits FF/A-MSDU just fine - it takes an 802.11 frame and will dutifully send the thing. So: * bump RX queue up from 1. Why's it 1? That's really silly. * Add the "software A-MSDU" encap capability bit. * bump the TX buffer size up so we can at least send A-MSDU frames. * track active frames submitted to the NIC - we can't make assumptions about how many are in flight in the NIC though. For 88E parts we could use per-packet TX indication, but for R92 parts we can't. So, just fake it somewhat. * Kick the transmit queue when we finish reception; try to avoid stalls. * Kick the FF queue a little more regularly. A-MSDU TX won't happen until the net80211 side is done, but atheros fast-frames support should now work. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; A-MSDU transmit.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

[urtwn] first cut of getting the fast-frames / amsdu support in shape. The urtwn hardware transmits FF/A-MSDU just fine - it takes an 802.11 frame and will dutifully send the thing. So: * bump RX queue up from 1. Why's it 1? That's really silly. * Add the "software A-MSDU" encap capability bit. * bump the TX buffer size up so we can at least send A-MSDU frames. * track active frames submitted to the NIC - we can't make assumptions about how many are in flight in the NIC though. For 88E parts we could use per-packet TX indication, but for R92 parts we can't. So, just fake it somewhat. * Kick the transmit queue when we finish reception; try to avoid stalls. * Kick the FF queue a little more regularly. A-MSDU TX won't happen until the net80211 side is done, but atheros fast-frames support should now work. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; A-MSDU transmit.

Replay r286410. Change KPI of how device drivers that provide wireless connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

urtwn driver fixes - missing include, free node references, shut down xfers first * include opt_wlan.h like a good little wlan driver; * add a function to free the mbufq /and/ the node references on it, or we will leak said node references; * free the mbufq upon NIC shutdown otherwise we may end up with a full list that we never begin transmit work on, and thus never drain it; * .. which frees it upon NIC detach too; * ensure urtwn_start() gets called after the completion of frame TX even if the pending queue is empty, otherwise transmit will stall. It's highly unlikely that the usb tx queue would be empty whilst the incoming send queue is full, but hey, who knows. This passes some iperf testing with and without the NIC being actively removed during said active iperf test. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; STA mode
