net: enetc: add support for the "Add" operation to VLAN filter table
The VLAN filter table contains configuration and control information for
each VLAN configured on the switch. Each VLAN entry includes the VLAN
port membership, which FID to use in the FDB lookup, which spanning tree
group to use, the egress frame modification actions to apply to a frame
exiting form this VLAN, and various configuration and control parameters
for this VLAN.
The VLAN filter table can only be managed by the command BD ring using
table management protocol version 2.0. The table supports Add, Delete,
Update and Query operations. And the table supports 3 access methods:
Entry ID, Exact Match Key Element and Search. But currently we only add
the ntmp_vft_add_entry() helper to support the upcoming switch driver to
add an entry to the VLAN filter table. Other interfaces will be added in
the future.
