should enable us to discard these frames if the hardware picks
other bogus items first. Lets see if we still get those jumbo
counters increasing still with this.

Jumbo frames would happen if we tell hardware we can support
a small 802.11 chunks of DMA'd frame, hardware would split RX'd
frames into parts and we'd have to reconstruct them in software.
This is done with USB due to the bulk size but with ath5k we
already provide a good limit to hardware and this should not be

Johannes Berg [Thu, 29 Apr 2010 07:53:29 +0000 (00:53 -0700)]
iwlwifi: rework broadcast station management

Currently, the broadcast station is managed along
with the interface type, rather than always being
present. That leads to a bug with injection -- it
is currently not possible to inject frames when
the only virtual interface is a monitor, because
in that the required broadcast station is missing.

Additionally, allocating and deallocating the
broadcast station's LQ all the time is wasteful,
and the code to support this is fairly complex.

So this changes completely the way we manage the
broadcast station. Rather than manage it along
with any interface, we now allocate it when we
bring the device up, and remove it again when we
bring the device down. When we bring the device
up, we don't immediately program the broadcast
station into it, instead we just mark it active
and rely on the next restore cycle to upload it
to the device. This works because an unassociated
RXON is always required at least once to set up
device parameters, which implies a reprogramming
of stations into the device.

As we now manage all stations properly, there no
longer is a need for forcing a clearing of them
via iwl_clear_ucode_stations(), which can become
a lot simpler.
