linux-next: manual merge of the net tree with the wireless-current tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Today's linux-next merge of the net tree got a conflict in
net/mac80211/rate.c between commit
5affcd6ba2036b59a4dee3f0576ae3584e92e4f1 ("mac80211: fix handling of
null-rate control in rate_control_get_rate") from the wireless-current
tree and commit 37eb0b164cf9fa9f70c8500926f5cde7c652f48e
("cfg80211/mac80211: Use more generic bitrate mask for rate control")
from the net tree.

John, I know you mentioned this, so I assume it will go away soon.

I fixed it up (I think - see below).
