Subject: [PATCH] udev: net_id: add support for phys_port_name attribute
(#4506)
Switch drivers uses phys_port_name attribute to pass front panel port
name to user. Use it to generate netdev names.
Signed-off-by: Jiri Pirko <jiri@mellanox.com>
(cherry picked from commit 4887b656c22af059d4e833de7b56544f24951184)
