408146ed57 Load firmware images directly from the filesystem (looks into /etc/firmware
directory by default) without requiring the user to load them by hand using
e.g iwicontrol.  Get rid of the old ioctl crud.
Updated iwi-firmware port coming soon.

46c34436a3 Be more robust when handling Rx interrupts. If we can't allocate and DMA map
a new mbuf, just discard the received frame and reuse the old mbuf.
This should fix kernel panics on high network traffic.

80e1a7127f o Use firmware extended scan command; this one doesn't crash when scanning
the 5GHz band.
o Enable 802.11a channels scanning for 2915ABG adapters.
o Fix a typo (negociated->negotiated).

With hints from NetBSD.

28a380736d Use phk's kernel unit number allocator to associate unique ids to neighbors
in an IBSS.  Store ids directly into ieee80211_node's instead of managing
our own private association table.  Idea and code by Sam Leffler.

ad4f426ef6 Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash.  Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

0b74a28506 o Add initial bits for IBSS support.
o Allow association with APs that do not broadcast SSID (with hints from
  Nick Hudson and Hajimu Umemoto).
o IFQ_DRV_PREPEND mbuf when h/w ring is full so it can be sent later.
o Increment if_oerrors when appropriate.
o Did some cleanup while I'm here.

fb533d55c6 Enhanced WME (802.11e) support. 2005-08-21 09:52:18 +00:00
Damien Bergamini
ec01dc2bbc Add some necessary bits for upcoming 802.11e support:
o management of multiple tx rings (up to 4)
o setting of WME IE in association requests

Some features are still missing though, like the possibility to override
the default cwmin/cwmax/asfn values of each tx queues.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

acea42415f o Clear device-specific PCI register 0x41 (Retry Timeout) during attach
and on resume (reported to fix issues with ACPI)
o Add monitor mode support
o Add WPA (802.11i) support (not tested extensively though!)
o Add a device specific sysctl to control the tx antenna (default to
  antenna diversity)
o Fix sensitivity setting
o Fix setting of the capinfo field when associating
o Temporarly disable 802.11a channels scanning that was causing firmware
  panics with 2915ABG adapters until I find a better fix.  This breaks
  802.11a support.
o Temporarly switch back to software WEP until I implement hardware
  encryption for AES and TKIP too.
