Subject: [PATCH net-next V1 08/18] net/mlx5: Introduce access functions to modify/query vport vlans
From: Saeed Mahameed <saeedm@...lanox.com>
Those functions are needed to notify the upcoming L2 table and SR-IOV
E-Switch(FDB) manager(PF), of the NIC vport (vf) vlan table changes.
preperation for ethernet sriov and l2 table management.
