2013-08-09ath9k: simplify ath_tx_form_aggrFelix Fietkau2-22/+12
The check for ATH_AMPDU_SUBFRAME_DEFAULT is unnecessary, since it's set to half the maximum BlockAck Window size, which is already the maximum value that h_baw could possibly have. Also remove unnecessary variables. Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2013-08-09mwifiex: add packet coalesce supportAmitkumar Karwar5-0/+254
Coalesce filters are configured in firmware based on settings received from cfg80211. Packet type which is required by firmware is determined based on provided patterns in a rule: Unicast: if pattern '01' with offset 0 is found Multicast: if pattern '33:33' or '01:00:5e' with offset 0 is found Broadcast: if pattern 'ff:ff:ff:ff' with offset 0 is found Some example coalesce configuration files: 1) Coalesce Rx data packets from 192.168.0.88 mac address of our device is 00:50:43:21:53:7A Source IP address offset comes out as 52 after following calculations: 32 bytes of HW 802.11 header + 8 bytes LLC + 12 bytes in IPV4 header till source IP address Destination mac is at offset 6 in HW header. delay=100 condition=1 patterns=01,6+00:50:43:22,10+53:7A,52+c0:a8:00:58 2) Coalesce all broadcast and multicast packets(Multiple packet types are not allowed in a single rule. Hence created separate rules) delay=400 condition=1 patterns=33:33 delay=400 condition=1 patterns=ff:ff:ff:ff Signed-off-by: Amitkumar Karwar <[email protected]> Signed-off-by: Bing Zhao <[email protected]> Signed-off-by: John W.

If no opmode is present during suspend/resume (i.e. if the iwldvm or iwlmvm isn't loaded) the driver crashes during resume, trying to call the rfkill notification. Avoid that, and also don't enable the rfkill interrupt in this case (to avoid crashing trying to handle the interrupt later.)
