2013-08-09ath9k: prepare queueing code for handling unaggregated trafficFelix Fietkau2-9/+14
- Allow ath_tx_get_tid_subframe to return non-AMPDU subframes. - Reset the tid paused state on aggregation stop - Initialize software queues even when HT is not supported Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2013-08-09ath9k: fix block ack window tracking checkFelix Fietkau2-7/+11
When a packet has been tracked as part of the BlockAck window and added to the hardware queue, it can end up back in the TID queue again with fi->retries still set to 0 (e.g. if the frame was filtered). Keep an extra bit for the BAW tracking status to fix this corner case. Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W. Linville <[email protected]>
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.

2013-08-07ath6kl: Fix invalid pointer access on fuzz testing with AP modeMohammed Shafi Shajakhan1-0/+3
In our Fuz testing, reference client corrupts the dest mac to "00:00:00:00:00:00" in the WPA2 handshake no 2. During driver init the sta_list entries mac addresses are by default "00:00:00:00:00:00". Driver returns an invalid pointer (conn) and the drver shall crash, if rxtids (aggr_conn) skb queues are accessed, since they would not be initialized.

2013-08-07ath10k: add SoC power save option to PCI features mapBartosz Markowski2-12/+21
Unify the PCI options location. By default the SoC PS option is disabled to boost the performance and due to poor stability on early HW revisions. In future we can remove the module parameter and turn on/off the PS for given hardware. This change also makes the pci module parameter for SoC PS static.
