ath9k: dynack: use authentication messages for 'late' ack
[ Upstream commit 3831a2a0010c72e3956020cbf1057a1701a2e469 ]
In order to properly support dynack in ad-hoc mode running
wpa_supplicant, take into account authentication frames for
'late ack' detection. This patch has been tested on devices
mounted on offshore high-voltage stations connected through
~24Km link
