Subject: [PATCH] mac80211: fix the multiple warnings for budding chipsets without ampdu_action defined
Date: Fri, 07 Dec 2012 12:19:34 +0530	[thread overview]
Message-ID: <50C1917E.2010407@posedge.com> (raw)

Warn once should suffice.

Eg: our driver doesn't support the ampdu_action yet, so
seeing a lot of warnings, hence the check for any
new drivers to avoid messing the kernel log.
