Subject: [PATCH NEXT] rtl8187: Increase RX queue depth
Date: Tue, 29 Oct 2013 17:06:41 -0500 [thread overview]
Message-ID: <1383084401-4593-1-git-send-email-Larry.Finger@lwfinger.net> (raw)
Under heavy load, the relatively small number of RX queue entries are
completely filled. With an increase from 16 to 32 entries, this condition
rarely happens.
