Subject: [PATCH v2 net-next 00/10] Configure the MTU on DSA switches

From: Vladimir Oltean <vladimir.oltean@....com>

This series adds support for configuring the MTU on front-panel switch
ports, while seamlessly adapting the CPU port and the DSA master to the
largest value plus the tagger overhead.

It also implements bridge MTU auto-normalization, as discussed with
Florian in the comments of v1.

Support was added for quite a number of switches, in the hope that this
series would gain some traction:
 - sja1105
 - felix
 - vsc73xx
 - b53 and rest of the platform

V1 of this series was submitted here:
