From dd4d3161d0f229031914f403721ced8cb64d4d52 Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Sun, 7 Feb 2016 12:50:35 +0200 Subject: iwlwifi: mvm: fix RSS key sizing The initialization and copying of the RSS secret key should not use ARRAY_SIZE as we need to initialize a dword array, and not a byte array. Fix also the hook maximum write size to allow writing a longer table - up to full indirection table size.
