Subject: [PATCH 4/7] rt2x00: Fix dead queue when skb allocation failed
Date: Mon, 11 Oct 2010 15:38:26 +0200	[thread overview]
Message-ID: <201010111538.27633.IvDoorn@gmail.com> (raw)
In-Reply-To: <201010111538.08677.IvDoorn@gmail.com>

When the RX skb allocation failed, we should recycle
the previously allocated skbuffer. By calling return
we would kill the RX queue completely since the
entry would be invalidated.
