Series [v2,1/3] mac80211: add ieee80211_is_tx_data helper function | expand

Commit Message

Philipp Borgers May 19, 2021, 12:20 p.m. UTC 
Use newly introduced helper function ieee80211_is_tx_data to check if
frame is a data frame. Takes into account that hardware encapsulation
can be enabled for a frame and therefore no ieee80211 header is present.
