linux-next: manual merge of the wireless-next tree with the wireless tree
From: Mark Brown
Date: Wed Sep 09 2026 - 08:20:17 EST
Hi all,
Today's linux-next merge of the wireless-next tree got conflicts in:
include/net/mac80211.h
net/mac80211/iface.c
net/mac80211/tx.c
between commit:
d4b31f7757d81 ("wifi: mac80211: don't allow injecting frames wider than the chanctx")
from the wireless tree and commits:
9d1365e96a920 ("wifi: mac80211: avoid trimming injected FCS twice")
a64a20fb270f2 ("wifi: mac80211: store the ack skb before building the header")
from the wireless-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.
