Subject: [PATCH 1/4] wlcore: set default_wep_key when configured
Date: Sun, 12 May 2013 12:35:28 +0300	[thread overview]
Message-ID: <1368351331-6914-1-git-send-email-eliad@wizery.com> (raw)

From: Yoni Divinsky <yoni.divinsky@ti.com>

When associating to an AP with WEP set the
default key upon association by implementing
the set_deafult_key_idx op.

Fixes auto-arp sent with wrong key_idx bug.
