Subject: linux-next: manual merge of the wireless-drivers-next tree with the
net-next tree
Hi Kalle,
Today's linux-next merge of the wireless-drivers-next tree got a
conflict in drivers/net/wireless/ath/ath10k/mac.c between commits
41fbf6e4f317 ("ath10k: enable IEEE80211_HW_SUPPORT_FAST_XMIT") and
df1404650ccb ("mac80211: remove support for IFF_PROMISC") from the
net-next tree and commits 548462133d98 ("ath10k: fix interrupt storm"),
cc9904e694fa ("ath10k: add hw connection monitor support") and
500ff9f9389d ("ath10k: implement chanctx API") (and a few others) from
the wireless-drivers-next tree.
I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).

Cheers,
