~25.6
25.5 1: Perform ‘local loopback’, i.e. loop back MAC’s RX back to TX
0: Normal operation
25.4 1: The switch will replace a NULL VID with a port VID (12 bits)
0: No replacement for a NULL VID
25.3 1: If the received packets are tagged, the switch will discard packets whose
VID does not match the ingress port’s PVID
0: No packets will be dropped
25.2 1: Disable 802.1p priority classification for ingress packets on port 1
0: Enable 802.1p priority classification
25.1 1: Disable Diffserv priority classification for ingress packets on port 1
0: Enable Diffserv priority classification
25.0 1: Disable port priority function
