2013-03-25wlcore: move handling from hardirq to the irq thread functionLuciano Coelho
Spin locks and completions are expensive in hard IRQ context and cause problems with RT kernels. In RT kernels, both spin locks and completions can schedule(), so we can't use them in hard irq context. Move handling code into the irq thread function to avoid that.

2013-03-25wlcore: use print_hex_dump_debug()Luciano Coelho
We were printing out all the hex dumps regardless of whether dynamic debugging was enabled or not. Now that print_hex_dump_debug() has been implemented, we can use that instead. Reported-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2013-03-25wlcore: consider dummy packets when tx queues are emptyArik Nemtsov
Don't ignore dummy packets when our queues are empty. This causes dummy packets never to be sent when traffic is not suspended by FW thresholds, which happens only in high Tx throughput situations. This may hurt Rx performance. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2013-03-25wlcore: correctly check state before regdomain confArik Nemtsov
The wlcore state was checked without the mutex being taken. This leads to WARN_ONs sometimes if a notification arrives when the driver is on, but the mutex is only taken after it is off. This usually happens if stopping the driver while connected to a network. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2013-03-25wlcore: AP-mode - recover security seq num for stationsArik Nemtsov
Save the sequence number of the broadcast AP link in the wlvif. For each connected station, save the sequence number in the drv_priv part of ieee80211_sta. Use the saved numbers on recovery/resume, with the obligatory increment on recovery. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2013-03-25wlcore: free AP global links properly on recoveryArik Nemtsov
Dont use free_sta() on AP global links. It would fail an internal check within the function and various structures within the link struct would not be reset. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2013-03-25wlcore: don't attempt to roam in case of p2pEyal Shapira
For STA we report beacon loss to higher levels so that wpa_s can attempt to roam without disconnecting. In case of P2P CLI we don't want to attempt roaming and instead disconnect immediately upon beacon loss. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2013-03-25wlcore: change warn on missing lock in wlcore_queue_xx funcsArik Nemtsov

2013-03-25wlcore: consolidate tx_seq handling on recoveryArik Nemtsov
Accumulate the total number of sent packets per-link to find out how far the encryption sequence number has progressed. Use this number as the initial security sequence number after recovery. This consolidates security sequence handling for both chip families, as we no longer have to rely on 12xx specific Tx completion. A fortunate side effect of this is correct management of seq numbers for AP roles and multi-role scenarios. When a link is removed we save the last seq number on a persistent part of the wlvif. This helps the data survive through recoveries/suspends, which also entail changes in the hlid of the link. This functionality is STA only currently.

2013-03-25wlcore: fix link count in single-link-PSM optimizationArik Nemtsov
commit 144614f3eebd7d only allowed a single active link when turning on the optimization, ignoring the fact that an AP has two additional global links. Use 3 links as an indication for a single active link. Use the FW PSM bits to verify the extra active link belongs to the AP role.
