IEEE 802.3x Transmit Direction Flow Control Enable
1 = enables transmit direction flow control feature.
0 = will not enable transmit direction flow control feature. The switch will not generate any flow
control packets.

IEEE 802.3x Receive Direction Flow Control Enable
1 = enables receive direction flow control feature.
0 = will not enable receive direction flow control feature. The switch will not react to any received
flow control packets.

Frame Length Field Check
1 = checks frame length field in the IEEE packets. If the actual length does not match, the packet
will be dropped (for Length/Type field < 1500).

Aggressive Back-Off Enable
1 = enable more aggressive back off algorithm in half-duplex mode to enhance performance. This
is not an IEEE standard.

Link Change Age
1 = link change from “link” to “no link” will cause fast aging (<800us) to age address table faster.
After an age cycle is complete, the age logic will return to normal (300 + 75 seconds).
Note: If any port is unplugged, all addresses will be automatically aged out.
