Hash key data
The hash key data for hash key type 7 is the contents of the 12-bit VLAN ID fields of all the VLAN tags in the frame.
Hash key data word 0 includes the contents of the VLAN ID field of the first VLAN tag. Hash key data word 1 includes the contents of the VLAN ID field of the second VLAN tag and so on. Like in the frame decoding process, a maximum of 3 VLAN tags are supported. Hash key data words that are not used are all zeros for hash key type 7.
