Subject: [PATCH net-next 3/3] sfc: stop setting dev_port

From: Bert Kenward <bkenward@...arflare.com>

Setting dev_port changes the device names allocated by systemd. Any devices
with a dev_port >0 will (in default distro configurations) have a suffix of
"d<port-number>" appended.

This is not something done by other drivers, and causes confusion for users.

Fixes: 8be41320f346 ("sfc: Add code to export port_num in netdev->dev_port")
