Subject: [PATCH 13/13] rt2x00: Add an error message when trying to send on a full queue
Date: Mon, 28 Mar 2011 13:35:51 +0200	[thread overview]
Message-ID: <201103281335.53224.IvDoorn@gmail.com> (raw)
In-Reply-To: <201103281335.23166.IvDoorn@gmail.com>

From: Helmut Schaa <helmut.schaa@googlemail.com>

We already tell mac80211 to stop the queue when we hit a certain
threshold. Hence, it shouldn't happen at all that a frame gets queued
for tx on a full queue. Add an error message for this case.
