From 80ca25711380c8eabe51eed875ca9432b4f8939e Mon Sep 17 00:00:00 2001 From: Thomas Pedersen Date: Mon, 21 Sep 2020 19:28:09 -0700 Subject: cfg80211: handle Association Response from S1G STA The sending STA type is implicit based on beacon or probe response content. If sending STA was an S1G STA, adjust the Information Element location accordingly.
