2011-02-28iwlwifi: remove duplicate initializationDan Carpenter
rate_mask is initialized again later so this can be removed. Btw, if rate_control_send_low(sta, priv_sta, txrc) returns false, that means that "sta" is non-NULL. That's why the second initialization of rate_mask is a little simpler than the first.

2011-02-25b43: fill PHY ctl word1 in TX header for N-PHYRafał Miłecki
This patch fixes tramissing on OFDM rates for PHYs 1 and 2. There is still something wrong with PHYs 3+. Tests has shown decreasing of performance on CCK rates by 1-2%, we have to live with that. Additionaly this noticeably reduces amount of PHY errors. They were mostly produced by auto-switching to higher rate for better performanced, which resulted in no transmit at all and PHY errors.

2011-02-25iwlagn: fix iwlagn_check_needed_chainsJohannes Berg
This function was intended to calculate the number of RX chains needed, but could only work where the AP's streams were asymmetric, i.e. 2 TX and 3 RX or similar. In the case where IEEE80211_HT_MCS_TX_RX_DIFF was not set, this function would calculate the wrong information. Additionally, mac80211 didn't pass through the required values at all, so it couldn't work anyway. Rewrite the logic in this function and add appropriate comments to make it readable.

2011-02-25mac80211: make tx() operation return voidJohannes Berg
The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.
