[PATCH net-next 3/7] net/mlx5e: Support VF vport link state control for SRIOV switchdev mode
From: Saeed Mahameed <hidden>
Date: 2016-11-21 13:07:14
Subsystem:
mellanox ethernet driver (mlx5e), mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers:

From: Or Gerlitz <redacted> Reflect the administative link changes done on the VF representor to the VF e-switch vport. This means that doing ip link set down/up commands on the VF rep will modify the e-switch vport state which in turn will make proper VF drivers to set their carrier accordingly.
