Subject: [PATCH net-next V10 2/4] General check for vlan ethernet types
Date: Tue, 2 Jun 2015 13:50:42 -0400 [thread overview]
Message-ID: <1433267444-26025-3-git-send-email-thomasfherbert@gmail.com> (raw)
In-Reply-To: <1433267444-26025-1-git-send-email-thomasfherbert@gmail.com>
This patch adds a function to check for vlan ethernet types. There is a
use case in openvswitch and it should be useful elsewhere.
