Message-Id: <20170526063740.8909-7-jiri@resnulli.us> Date: Fri, 26 May 2017 08:37:28 +0200 From: Jiri Pirko <jiri@...nulli.us> To: netdev@...r.kernel.org Cc: davem@...emloft.net, idosch@...lanox.com, mlxsw@...lanox.com, stephen@...workplumber.org, nikolay@...ulusnetworks.com 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.
