      mac80211: pass vif param to conf_tx() callback · 8a3a3c85
      由 Eliad Peller 提交于 
      tx params should be configured per interface.
add ieee80211_vif param to the conf_tx callback,
and change all the drivers that use this callback.

The following spatch was used:

	ops.conf_tx = conf_tx_op;

      mwl8k: Reducing extra_tx_headroom for tx optimization in AP mode · ff776cec
      由 Yogesh Ashok Powar 提交于 
      The tx_headroom required for mwl8k driver is 32 bytes and it
can use the space for 802.11 header received from mac80211.
mwl8k considers the smallest 802.11 frame (CTS2self of 10
bytes) that can be received from mac80211  to compute the
extra_tx_headroom as 22 (32 - 10) bytes.

When the wireless interface is part of bridge, this
extra_tx_headroom requirement results in a memcpy in
mac80211 (in function pskb_expand_head) for all the data
frames needing L2 forwarding/bridging, when NET_SKB_PAD is
defined as 32. This patch reduces the extra_tx_headroom by
8 bytes so that memcpy of data frames in mac80211 is
avoided in this case.

The resize will be required in driver for frames with 802.11
header size of less than 18 bytes.

      mac80211: make tx() operation return void · 7bb45683
      由 Johannes Berg 提交于 
      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.
