[dpdk-dev] [PATCH v2 1/1] net/e1000: igbvf VLAN offload implementation

[Renata Saiakhova <Renata.Saiakhova@ekinops.com>]

igbvf_vlan_offload_config and igbvf_vlan_offload_set primal
implementation, setting vlan filter mask at igbvf_dev_start time.
Without the above a vlan filter for igbvf is not functional.
