Subject: [PATCH net-next 09/18] net/mlx5e: Write UC/MC list and promisc mode into vport context
From: Saeed Mahameed <saeedm@...lanox.com>
Each Vport/vNIC must notify underlying e-Switch layer
for UC/MC list and promisc mode updates, in-order to update
l2 tables and SR-IOV FDB tables.
We do that at set_rx_mode ndo.
preperation for ethernet-SRIOV and l2 table management.
