1 = advertise the switch’s flow control capability via auto
negotiation.
0 = will not advertise the switch’s flow control capability via
auto negotiation.
1 = enable auto negotiation on port 2
0 = disable auto negotiation on port 2
1 = force port 2 to 100BT if P2ANEN = 0
0 = force port 2 to 10BT if P2ANEN = 0
1 = port 2 default to full duplex mode if P2ANEN = 1 and auto
negotiation fails. Force port 2 in full duplex mode if P2ANEN
= 0.
0 = port 2 default to half duplex mode if P2ANEN = 1 and
auto negotiation fails. Force port 2 in half duplex mode if
P2ANEN = 0.
1 = always enable (force) port 2 flow control feature
0 = port 2 flow control feature enable is determined by auto
negotiation result.
