From 45cbad6a1299842b5ae9a8a9c09630af063692f8 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Tue, 25 Jan 2011 12:21:22 +0200 Subject: [PATCH] cfg80211: Allow non-zero indexes for device specific pair-wise ciphers Some vendor specific cipher suites require non-zero key indexes for pairwise keys, but as of currently, the cfg80211 does not allow it. As validating they cipher parameters for vendor specific cipher suites is the job of the driver or hardware/firmware, change the cfg80211 to allow also non-zero pairwise key indexes for vendor specific ciphers.
