2009-11-28ath9k: Proper padding/unpadding for the TX/RX path.Benoit Papillault
Software padding is done on the TX path and software unpadding is done on the RX path. This patch corrects the position where the padding occurs. A specific function computes the pad position and this function is used in the TX and RX path. This patch has been tested by generating every possible 802.11 frames with every possible frame_control field and a varying length. This patch is useful for analyzing non standard 802.11 frames going over the air Signed-off-by: Benoit Papillault <benoit.papillault@free.fr> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-11-28ath9k: fix processing of TX PS null data framesLuis R. Rodriguez
When mac80211 was telling us to go into Powersave we listened and immediately turned RX off. This meant hardware would not see the ACKs from the AP we're associated with and hardware we'd end up retransmiting the null data frame in a loop helplessly. Fix this by keeping track of the transmitted nullfunc frames and only when we are sure the AP has sent back an ACK do we go ahead and shut RX off.

2009-11-28iwmc3200wifi: 802.11n Tx aggregation supportSamuel Ortiz
To support 802.11n Tx aggregation support with iwmc3200 wifi, we have to handle the UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification from the UMAC. Before sending an AddBA, the UMAC synchronizes with the host in order to know what is the last Tx frame it's supposed to receive before it will be able to start the actual aggregation session. We thus have to keep track of the last sequence number that is scheduled for transmission on a particular RAxTID, send an answer to the UMAC with this sequence number. The UMAC then does the BA negociation and once it's done with it sends a new UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification to let us know that we can resume the Tx flow on the specified RAxTID.

2009-11-28wl1271: fix the inetdev notifier callback return valuesLuciano Coelho
The wl1271_dev_notify() was returning 0 or -ENODEV, when it should return NOTIFY_* instead. Now we use NOTIFY_DONE when we didn't handle the event or NOTIFY_OK when we have handled it. For inetdev notifications, it doesn't matter whether we use NOTIFY_DONE or NOTIFY_OK, because it ignores the return value of the call to blocking_notifier_call_chain(). But the notify.h header says that NOTIFY_DONE is "Don't care" and NOTIFY_OK is "Suits me", so that seems to be the right way to do it.
