From d748b4642a53cd1ead303f9e2b008295391466b7 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 28 Mar 2012 11:04:23 +0200 Subject: mac80211: remove antenna_sel_tx TX info field This field is never set to anything non-zero in mac80211, so we should be able to remove it. Unfortunately though, the iwlwifi and iwlegacy drivers use it for their internal TX status processing (which shouldn't be using the rate control API to start with), so add a new field "status.antenna" for them, at least for now. In the future, I plan to use the new field to hold the hardware queue, while the SKB's queue mapping holds the AC. Signed-off-by: Johannes Berg Signed-off-by: John W.
