Subject: [PATCH 29/57] net-next: ethernet: mediatek: add CDM able to recognize
|
|
the tag for DSA
|
|
|
|
The patch adds the setup for allowing CDM can recognize these packets with
|
|
carrying port-distinguishing tag. Otherwise, these tagging packets will be
|
|
handled incorrectly by CDM. The setup is also working out for general
|
|
untag packets as well.
