From: Gertjan van Wingerde Date: Mon, 23 Nov 2009 21:44:52 +0000 (+0100) Subject: rt2x00: Centralize setting of extra TX headroom requested by rt2x00. X-Git-Tag: firefly_0821_release~9833^2~3968^2~2^2~46 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e6218cc47bd54710dc523e8c983ceddba625e3ae;p=firefly-linux-kernel-4.4.55.git rt2x00: Centralize setting of extra TX headroom requested by rt2x00. 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.
