Subject: [PATCH net-next 3/5] net: inline dev_queue_xmit()
Date: Thu, 28 Apr 2022 11:58:46 +0100 [thread overview]
Message-ID: <99bf2b824f3a4e0428a8be81c8685afe78ffa207.1651141755.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1651141755.git.asml.silence@gmail.com>
Inline dev_queue_xmit() and dev_queue_xmit_accel(), they both are small
proxy functions doing nothing but redirecting the control flow to
__dev_queue_xmit().
