Subject: [PATCH net-next 5/6] doc, net: Remove instruction to set net_device::trans_start
Date: Fri, 6 Apr 2012 01:40:06 +0100 [thread overview]
Message-ID: <1333672806.2652.28.camel@bwh-desktop.uk.solarflarecom.com> (raw)
In-Reply-To: <HEAD <1333672667.2652.22.camel@bwh-desktop.uk.solarflarecom.com>
Commit 08baf561083bc27a953aa087dd8a664bb2b88e8e ('net:
txq_trans_update() helper') made it unnecessary for most drivers to
set net_device::trans_start (or netdev_queue::trans_start).
