From 7cc4573e85cd7f7179fdfe0b7d3114a4fbdd6f2a Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Mon, 9 Mar 2015 14:24:17 +0100 Subject: [PATCH] ath10k: fix WPA crypto Commit 370e567363e6 ("ath10k: fix broken traffic for 802.1x in client mode") introduced a regression on WPA crypto. All keys were treated as if they were WEP which resulted in WPA being incorrectly installed to fw/hw and subsequently no traffic.
