The hardware rx-filter was essentially disabled, because of a serve, yet unidentifiable problem with iwlagn. Due to these circumstances the driver and mac80211 were left with the job of filtering. This is very unfortunate and has proven to be expensive in terms of latency, memory and load. Therefore the new 1.8.8.3 firmware introduces a flexible filtering infrastructure which allows the driver to offload some of the checks (FCS & PLCP crc check, RA match, control frame filter, etc...) whenever possible. Note: This patch also includes all changes to the shared headers files since the inclusion. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.
