Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either.

MFp4 changes to fix locking issues and correct reference count handling of station entries in hostap mode: Input path: o driver is now expected to find the node associated with the sender of a received frame; use ic_bss if none is located o driver passes the (referenced) node into ieee80211_input for use within the wlan module and is responsible for cleaning up on return o the antenna state is no longer passed up with each frame; this is now considered driver-private state and drivers are responsible for keeping it in the driver-private part of a node Output path: Revamp output path for management frames to eliminate redundant locking that causes problems and to correct reference counting bogosity that occurs when stations are timed out due to inactivity (in AP mode). On output the refcnt'd node is stashed in the pkthdr's recvif field (yech) and retrieved by the driver. This eliminates an unref/ref scenario and related node table unlock/lock due to the driver looking up the node. This is particularly important when stations are timed out as this causes a lock order reversal that can result in a deadlock. As a byproduct we also reduce the overhead for sending management frames (minimal). Additional fallout from this is a change to ieee80211_encap to return a refcn't node for tieing to the outbound frame. Node refcnts are not reclaimed until after a frame is completely processed (e.g. in the tx interrupt handler). This is especially important for timed out stations as this deref will be the final one causing the node entry to be reclaimed. Additional semi-related changes: o replace m_copym use with m_copypacket (optimization) o add assert to verify ic_bss is never free'd during normal operation o add comments explaining calling conventions by drivers for frames going in each direction o remove extraneous code that "cannot be executed" (e.g. because pointers may never be null)

MFp4 changes to fix locking issues and correct reference count handling of station entries in hostap mode: Input path: o driver is now expected to find the node associated with the sender of a received frame; use ic_bss if none is located o driver passes the (referenced) node into ieee80211_input for use within the wlan module and is responsible for cleaning up on return o the antenna state is no longer passed up with each frame; this is now considered driver-private state and drivers are responsible for keeping it in the driver-private part of a node Output path: Revamp output path for management frames to eliminate redundant locking that causes problems and to correct reference counting bogosity that occurs when stations are timed out due to inactivity (in AP mode). On output the refcnt'd node is stashed in the pkthdr's recvif field (yech) and retrieved by the driver. This eliminates an unref/ref scenario and related node table unlock/lock due to the driver looking up the node. This is particularly important when stations are timed out as this causes a lock order reversal that can result in a deadlock. As a byproduct we also reduce the overhead for sending management frames (minimal). Additional fallout from this is a change to ieee80211_encap to return a refcn't node for tieing to the outbound frame. Node refcnts are not reclaimed until after a frame is completely processed (e.g. in the tx interrupt handler). This is especially important for timed out stations as this deref will be the final one causing the node entry to be reclaimed. Additional semi-related changes: o replace m_copym use with m_copypacket (optimization) o add assert to verify ic_bss is never free'd during normal operation o add comments explaining calling conventions by drivers for frames going in each direction o remove extraneous code that "cannot be executed" (e.g. because pointers may never be null)

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

MFp4 changes to fix locking issues and correct reference count handling of station entries in hostap mode: Input path: o driver is now expected to find the node associated with the sender of a received frame; use ic_bss if none is located o driver passes the (referenced) node into ieee80211_input for use within the wlan module and is responsible for cleaning up on return o the antenna state is no longer passed up with each frame; this is now considered driver-private state and drivers are responsible for keeping it in the driver-private part of a node Output path: Revamp output path for management frames to eliminate redundant locking that causes problems and to correct reference counting bogosity that occurs when stations are timed out due to inactivity (in AP mode). On output the refcnt'd node is stashed in the pkthdr's recvif field (yech) and retrieved by the driver. This eliminates an unref/ref scenario and related node table unlock/lock due to the driver looking up the node. This is particularly important when stations are timed out as this causes a lock order reversal that can result in a deadlock. As a byproduct we also reduce the overhead for sending management frames (minimal). Additional fallout from this is a change to ieee80211_encap to return a refcn't node for tieing to the outbound frame. Node refcnts are not reclaimed until after a frame is completely processed (e.g. in the tx interrupt handler). This is especially important for timed out stations as this deref will be the final one causing the node entry to be reclaimed. Additional semi-related changes: o replace m_copym use with m_copypacket (optimization) o add assert to verify ic_bss is never free'd during normal operation o add comments explaining calling conventions by drivers for frames going in each direction o remove extraneous code that "cannot be executed" (e.g. because pointers may never be null)

MFp4 changes to fix locking issues and correct reference count handling of station entries in hostap mode: Input path: o driver is now expected to find the node associated with the sender of a received frame; use ic_bss if none is located o driver passes the (referenced) node into ieee80211_input for use within the wlan module and is responsible for cleaning up on return o the antenna state is no longer passed up with each frame; this is now considered driver-private state and drivers are responsible for keeping it in the driver-private part of a node Output path: Revamp output path for management frames to eliminate redundant locking that causes problems and to correct reference counting bogosity that occurs when stations are timed out due to inactivity (in AP mode). On output the refcnt'd node is stashed in the pkthdr's recvif field (yech) and retrieved by the driver. This eliminates an unref/ref scenario and related node table unlock/lock due to the driver looking up the node. This is particularly important when stations are timed out as this causes a lock order reversal that can result in a deadlock. As a byproduct we also reduce the overhead for sending management frames (minimal). Additional fallout from this is a change to ieee80211_encap to return a refcn't node for tieing to the outbound frame. Node refcnts are not reclaimed until after a frame is completely processed (e.g. in the tx interrupt handler). This is especially important for timed out stations as this deref will be the final one causing the node entry to be reclaimed. Additional semi-related changes: o replace m_copym use with m_copypacket (optimization) o add assert to verify ic_bss is never free'd during normal operation o add comments explaining calling conventions by drivers for frames going in each direction o remove extraneous code that "cannot be executed" (e.g. because pointers may never be null)

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

wi_newstate(struct ieee80211com *ic, enum ieee80211_state nstate, int arg)
Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.
