This register defines the default value for the VLAN Ethertype and control word when VLAN tags are
automatically inserted by the eTSEC, and no per-frame VLAN data is supplied by software. On receive,
this register defines a customizable VLAN Ethertype for automatic deletion. Note that an Ethertype of
0x8808 (Control Word) is not permitted as a custom VLAN tag. Frames with an Ethertype of 0x8808 are
dropped by the receiver. In the case of frames containing stacked VLAN tags, this register defines the tag
associated with the outer or metropolitan area VLAN.

describes the fields of the DFVLAN register.
This is the default Ethertype used to tag VLAN frames. On transmit, this tag is inserted ahead of the VLAN
control word; TAG should be set to 0x8100 for IEEE 802.1Q VLAN. On receive, an Ethertype matching TAG or
an Ethertype of 0x8100 marks a VLAN-tagged frame.
Note that if using DFVLAN to set a custom ethertype (that is, using a value other than 0x8100), packets
received with a custom tag are not counted by any of the RMON counters. Affected counters include TRMGV,
RMCA, RBCA, RXCF, RXPF, RXUO, RALN, RFLR, ROVR, RJBR, TMCA, TBCA, TXPF, TXCF.
This is the default value used for the IEEE Std. 802.1Q canonical format indicator.
This is the default value used for the virtual-LAN identifier in VLAN-tagged frames. A value of zero is defined
as the null VLAN, however field PRI may be still set independently.
This is the default value used for the IEEE Std. 802.1p frame priority.
