389fb0b432 o acknowledge interrupts early in the interrupt handler
o stop processing interrupts after a firmware fatal error or a radio kill
o clarify the possible values for the 'antenna' sysctl.
o by default, let the firmware do antenna diversity.
  the  firmware will periodically switch to another antenna to evaluate the
  signal quality.

a4f5ae8ad6 Don't use /etc/firmware. /etc is for configuration files only.
Use /boot to store firmware files instead.

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.

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.

the 5GHz band.

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.
