Emmanuel noticed that there's no explicit checking that prevents the driver from attempting to issue multiple synchronous commands at the same time and wrote a patch to check. However, his patch warns only if a collision actually happened, an unlikely thing since the driver mutex should be held for synchronous command submissions. So instead of checking that a collision happened add a check that the mutex is held which ensures that collisions can't happen. Signed-off-by:

After calibrating radio you can find few PHY writes in MMIO dumps: phy_read(0x0009) -> 0x0000 phy_write(0x01ce) <- 0x03dd phy_write(0x01cf) <- 0x03d9 phy_write(0x01d0) <- 0x03d5 phy_write(0x01d1) <- 0x0424 phy_write(0x01d2) <- 0x0429 phy_write(0x01d3) <- 0x042d By comparing to N-PHY code we found out that they are PHY tables for channel switching plus band info read at the beginning.

Use the tx_frames_pending() driver callback to determine if Tx frames are pending for its internal queues. If so postpone the dynamic PS timeout to avoid interrupting Tx traffic. The commit e8306f98 enabled this behavior for drivers with IEEE80211_HW_PS_NULLFUNC_STACK. We enable this for all drivers supporting dynamic PS. This patch helps improve performance in noisy environments. Signed-off-by:

Prior to a5ffddb7 "mwifiex: remove casts of void pointers" the code assumed that the data_buf parameter could be a NULL pointer. The patch preserved some NULL checks but not consistently, so there was a potential for NULL dereferences and it changed the behavior. This patch restores the original behavior. Signed-off-by:

The received tx status of aggregated frame without BlockAck may cause deaf state in AR5416 cards. So the driver does a reset to recover. When this happens, we release the pcu_lock before doing a reset as ath_rest acquires pcu_lock. This is ugly and also not atomic. Fixing this addresses the TX DMA failure also. ath_tx_complete_aggr can be called from different paths which takes different variants of spin_lock. This patch also addresses the following warning.

The edma based (AR9003 family) chips update tx status descriptors in a common ring buffer for all transmitted frames. Whenever tx interrupt is raised, the descriptors are processed and tx status index is moved. The complete tx stauts ring are updated with beacons tx status when there are no data frames to be sent for a period of time. In this state, transmitting data frames causes the driver to wait for the tx status on an incorrect tx status index though the status was updated by hw properly. The driver detects this condition as a h/w hang and does unnecessary chip resets. This issue was orginally reported in adhoc mode while sending frames after an idle time. Signed-off-by:

When forming a Rx BA session, sometimes the ADDBA response gets lost. This leads to a situation where the session is configured locally, but doesn't exist on the remote side. Subsequent ADDBA requests are declined by mac80211. Fix this by assuming the session state of the initiator is the correct one. When receiving an unexpected ADDBA request on a TID with an active Rx BA session, delete the existing one and establish a new session. Signed-off-by:

Advertise only user-requested bitrates in a HW scan. Note that the hw_scan API doesn't currently have a way of asking for a specific probe request bitrate, so we might end up using a bitrate that we don't advertise as supported. I'll fix that later. Also add a hexdump printk to hwsim to verify this. Signed-off-by:
