2013-08-13NFC: pn533: Fix hardware busy loop when establishing the LLCP linkSamuel Ortiz
By using the standard setting for the regular pn533 dongles, we no longer wait for ever for an ATR_RES. Without this, a failing ATR_REQ will put the hardware into a busy loop, constantly waiting for an ATR_RES. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-08-09ath9k: use software queueing for multicast trafficFelix Fietkau
Create a per-vif dummy node entry for keeping the multicast software queues. This helps in setups with a lot of mulitcast traffic that could otherwise potentially drown out unicast traffic to stations. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-08-09ath9k: improve tx scheduling fairnessFelix Fietkau

2013-08-09ath9k: use software queues for un-aggregated data packetsFelix Fietkau
This is a first step for improving fairness between legacy and 802.11n traffic, and it should also improve reliability of resets and channel changes by keeping the hardware queue depth very short. When an aggregation session is torn down, all packets in the retry queue will be removed from the BAW and freed. For all subframes that have not been transmitted yet, the A-MPDU flag will be cleared, and a sequence number allocated. This ensures that the next A-MPDU session will get the correct initial sequence number. This happens both on aggregation session start and stop.

2013-08-09ath9k: always clear ps filter bit on new assocFelix Fietkau

2013-08-09ath9k: fix clearing expired A-MPDU subframes in tx completionFelix Fietkau
When the tid aggregation state has been marked as inactive, free completed tx packets immediately. When a new aggregation session has not been initialized yet, the BAW checks do not recognize it as expired. Might fix potential stalls in setting up a new aggregation session.

2013-08-09ath9k: prepare queueing code for handling unaggregated trafficFelix Fietkau

2013-08-09ath9k: fix block ack window tracking checkFelix Fietkau
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 <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-08-09ath9k: simplify ath_tx_form_aggrFelix Fietkau
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.

2013-08-09mwifiex: add packet coalesce supportAmitkumar Karwar
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.
