+Subject: [PATCH 1/3] rt2x00: Centralize setting of extra TX headroom requested by rt2x00.
+
+commit e6218cc47bd54710dc523e8c983ceddba625e3ae upstream.
+
+Set the value of extra_tx_headroom in a central place, rather than in each
+of the drivers. This is preparatory for taking alignment space into account
+in the TX headroom requested by rt2x00.

+Subject: [PATCH 3/3] rt2x00: Properly request tx headroom for alignment operations.
+
+commit 7a4a77b7771164d61ce702a588067d1e1d66db7c upstream.
+
+Current rt2x00 drivers may result in a "ieee80211_tx_status: headroom too
+small" error message when a frame needs to be properly aligned before
+transmitting it.
+This is because the space needed to ensure proper alignment isn't
+requested from mac80211.
+Fix this by adding sufficient amount of alignment space to the amount
+of headroom requested for TX frames.

+
+Add a definition of the amount of TX headroom reserved by mac80211 itself
+for its own purposes. Also add BUILD_BUG_ON to validate the value.
+This define can then be used by drivers to request additional TX headroom
+in the most efficient manner.
