| Subject: 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 |
