Description
Double word-wide bit vector specifying 32 bits in the VLAN filter table.
There is one register per 32 bits of the VLAN Filter table. The size of the word array
depends on the number of bits implemented in the VLAN filter table. Software must
mask to the desired bit on reads and supply a 32-bit word on writes.
All accesses to this table must be 32-bit.
The algorithm for VLAN filtering via the VFTA is identical to that used for the multicast
table array.
These registers' addresses have been moved from where they were located in previous
devices. However, for backwards compatibility, these registers can also be accessed at
their alias offsets of 0x00600-0x006FC
