Subject: linux-next: manual merge of the net-next tree with the mac80211
 tree

Hi all,

Today's linux-next merge of the net-next tree got a conflict in:

  net/mac80211/debugfs.c
  include/net/mac80211.h

between commit:

  7c181f4fcdc6 ("mac80211: add ieee80211_hw flag for QoS NDP support")

from the mac80211 tree and commit:

  94ba92713f83 ("mac80211: Call mgd_prep_tx before transmitting deauthentication")

from the net-next tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
