Message-Id: <20170526063740.8909-7-jiri@resnulli.us>

Subject: [patch net-next 06/18] mlxsw: spectrum_router: Replace vPorts with Port-VLAN
From: Ido Schimmel <idosch@...lanox.com>
We're going to get rid of vPorts completely later in the patchset, but
the router code is self-contained, so it's a good candidate to start the
transition with.
Convert all the functions that expects to operate on a vPort to operate
on a Port-VLAN instead.
