Subject: [PATCH] ath9k: dynack: use authentication messages for 'late' ack
|
||
|
|
|
||
|
|
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
