DESCRIPTION
RESERVED
802.3x Flow control frame recognition control
0: check for MAC control frame DA MAC address in addition to the MAC control type field
1: check only the MAC control type field
Setting for maximum length of packet that received
0: 1518 byte
1: 1522 byte
RESERVED
Software Reset (Only reset the switch kernel)
0: active
1: disable
Back-off algorithm selection
0: disable. Device will perform the IEEE standard exponential back off algorithm when a
collision occurs.
1: enable. When collisions occur, the MACs will back off up to 7 slots.
Note :: SuperMac v.s. FlowCtrl
0: stop generate JAM patterns after some collision that is defined by MaxJam[5:0]
1: Never stop back-pressure (Note: Only availible for Ethernet..Not FastEternet)
