Subject: [PATCH] ath6kl: disallow WoW with multiple vifs
Date: Thu, 19 Apr 2012 16:29:19 -0700	[thread overview]
Message-ID: <1334878159-7713-1-git-send-email-c_tpeder@qca.qualcomm.com> (raw)

The ath6kl fw does not have enough memory to support the WoW filters of
more than one vif. Disallow WoW suspend if this is the case.
