====================
mlx5-uplink-rep-2018-12-15

Or Gerlitz says:

This series is essentially a cleanup to align with the rest of the NIC
switchdev drivers and make us
more robust and clear/n: currently the PF netdev serves as the mlx5
e-switch uplink netdev
representor when going into switchdev mode and back as plain NIC
netdev when going out.
This causes some irregularities and misc troubles.

Move to use dedicated uplink rep, as we have for the VF vports.

The uplink rep netdev does has sysfs link and supports the sriov vf
mac ndo, these two are in
use by libvirt and other orchestrators, It also has richer ethtool
support to allow controlling the
port link & mtu along with supporting dcb and plugging into the mlx5
lag logic.
