Subject: [PATCH net-next 15/27] net: inline dev_queue_xmit()
Date: Sun,  3 Apr 2022 14:06:27 +0100	[thread overview]
Message-ID: <aad78b4885b5c5c7aeded24f7e0c2cc5e108e696.1648981571.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1648981570.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().
