Subject: [PATCH v2 net-next 07/22] ether: Add dedicated Ethertype for pseudo-802.1Q DSA tagging
Date: Wed, 10 Apr 2019 03:56:45 +0300 [thread overview]
Message-ID: <20190410005700.31582-8-olteanv@gmail.com> (raw)
In-Reply-To: <20190410005700.31582-1-olteanv@gmail.com>
With the newly added DSA_TAG_PROTO_8021Q, switch devices that don't
support a native insertion/extraction header on the CPU port may still
enjoy the benefits of port isolation with a custom VLAN tag.
For this, they need to have a customizable TPID in hardware and a new
Ethertype to distinguish between real 802.1Q traffic and the private
tags used for port separation.
