Subject: [PATCH] mac80211: fix authentication with iwlwifi/mvm
|
||
|
|
|
||
|
|
commit be8c827f50a0bcd56361b31ada11dc0a3c2fd240 upstream.
|
||
|
|
|
||
|
|
The original patch didn't copy the ieee80211_is_data() condition
|
||
|
|
because on most drivers the management frames don't go through
|
||
|
|
this path. However, they do on iwlwifi/mvm, so we do need to keep
|
||
|
|
the condition here.
