Subject: mac80211: Do not check for valid hw_queues for P2P_DEVICE
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0ef24e528f27683620d78c3393b3df73d804828c;p=linux-beck.git

mac80211: Do not check for valid hw_queues for P2P_DEVICE

A P2P Device interface does not have a netdev, and is not
expected to be used for transmitting data, so there is no
need to assign hw queues for it.
