Two queues / port for QoS purpose
Port-base, 802.1p and IP ToS priority
Store & forward architecture and Performs forwarding and filtering at non-blocking full wire speed
Supports aging function
Supports 802.3x flow control for full duplex and back-pressure for half duplex in case buffer is full
Support packet length up to 1536 bytes
Support Broadcast storm filter
Support port-base VLAN
Tag/Untagged function on each MAC.
Support five Smart counters on each MAC.
Support 16 entry of packet classify and marking or filtering for TCP port number
Provide TX1FX Converter mode with fault propagation and redundant capability by use of two AT8993.
Short latency on the converter mode.
