The frames were Mesh PERR frames, and some debugging showed an empty control block with just the vif pointer: > [ 562.522682] XXX txinfo: 00000000: 00 00 00 00 00 00 00 00 00 00 00 > 00 00 00 00 00 ................ > [ 562.522688] XXX txinfo: 00000010: 00 00 00 00 00 00 00 00 54 b8 f2 > db 00 00 00 00 ........T....... > [ 562.522693] XXX txinfo: 00000020: 00 00 00 00 00 00 00 00 00 00 00 > 00 00 00 00 00 ................ Set the IEEE80211_TX_INTFL_NEED_TXPROCESSING flag to ensure that rate control gets run before the frame is sent.
