Write to Register 110 (0x6E) with 0x14 (read VLAN table selected)
Write to Register 111 (0x6F) with 0x02 (trigger the read operation and VID=8, 9, 10, 11 indirect address)
Read Register 117 (0x75), (register117[7:2] are bits 5-0 of VLAN VID=2 entry)
Read the VLAN set that contains VID=8, 9, 10, 11.
Read the VLAN set first by the indirect data registers 114, 115, 116, 117, 118, 119, 120.
Modify the indirect data registers bits [38-26] by the register 116 bit [6-0] and register 117 bit [7-2] as
Write to Register 116 (0x74), (register116[6:0] are bits 12-6 of VLAN VID=10 entry)
Write to Register 117 (0x75), (register117[7:2] are bits 5-0 of VLAN VID=10 entry)
Then write the indirect control and address registers
Write to Register 110 (0x6E) with 0x04 (write VLAN table selected)
Write to Register 111 (0x6F) with 0x02 (trigger the write operation and VID=8, 9, 10, 11 indirect address)
