o call firmware_put() early to release the firmware module
o on firmware panics or watchdog timeouts, schedule a task to reinitialize
the interface (we may sleep in iwi_init())
o discard oversized rx frames
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.
o Change MEM_READ_1/MEM_READ_4 into macros (move them to if_iwireg.h)
o Add support for association LED
o Silently discard f/w notifications that are unknown (fixes spurious
"unknown notification 15" in logs with latest firmware)
o Fix scanning of 5GHz channels
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.

This should fix kernel panics on high network traffic.

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.
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.

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.
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.

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.

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.
