FS#1467 - ieee80211_tx_status: headroom too small

I've detected that the error only happens when using 4.14 kernel and an ath10k radio that is part of a bridge. This is an example brctl output where wlan0 and wlan1 are inside br-lan bridge:

root at LEDE:~# brctl show
bridge name	bridge id		STP enabled	interfaces
br-lan		9000.04f021132a4a	no		eth0.1
							eth0.2
							wlan0



If the wireless interface is not part of a bridge, it works correctly and no errors are shown.

Maybe this is a kernel related issue?
