Subject: [PATCH net-next 10/13] net: enetc: move generic VLAN hash filter functions to enetc_pf_common.c
Since the VLAN hash filter of ENETC v1 and v4 is the basically same, the
only difference is the offset of the VLAN hash filter registers. So, the
.set_si_vlan_hash_filter() hook is added to struct enetc_pf_ops to set
the registers of the corresponding platform. In addition, the common VLAN
hash filter functions enetc_vlan_rx_add_vid() and enetc_vlan_rx_del_vid()
are moved to enetc_pf_common.c.
