VLAN Tag Replace
For replacing a VLAN tag that exists in a VLAN tagged MAC frame with a new VLAN tag,
execute the VLAN tag append and the VLAN tag strip procedures on the same MAC frame (see
Section 7.1.6
).

4.2.3
Network Transmission
The IXF1002 will start to transmit the packet if there is enough data on the transmit FIFO
according to the programmable transmission threshold (TX_TSHD<TSD>), or if the full packet is
loaded onto the transmit FIFO.
If the packet is transmitted successfully, the next packet loaded onto the FIFO is transmitted onto
the network, using the programmable IPG_VAL<IPG> gap between them.
4.2.4
FIFO Underflow
In case of an underflow error, the IXF1002 can be programmed to stop or continue working. By
default (error continue mode) the IXF1002 will continue with the next packet loaded after an
underflow. In this mode the IX Bus will behave the same way with or without an underflow. In
both modes the appropriate statistics counters will be updated.
Following an underflow, packet transmission is truncated. The GMII error signal terr will be
asserted or a symbol error will be generated (GPCS mode) in the last data byte. A bad CRC will be
appended to the packet, if the IXF1002 is programmed to append the CRC. If the underflow occurs
before the transmission of 60 bytes, padding is added.
