From 3cb10943fc60b4349a4d7865bdd579bc5c8eaf73 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 22 Jan 2015 21:38:45 +0100 Subject: [PATCH] ath10k: use IEEE80211_HW_SW_CRYPTO_CONTROL The ath10k driver only supports HW crypto (except for management frames or so - CMAC needs to be done in software). Make it use the new IEEE80211_HW_SW_CRYPTO_CONTROL flag to ensure mac80211 doesn't erroneously attempt to use software crypto. Taking through my tree after Kalle's ACK to avoid breaking the ath10k driver with the next crypto patches.
