Description
= 0, disable auto negotiation; speed and duplex
are determined by bits 6 and 5 of this register.
= 1, auto negotiation is on
= 1, forced 100BT if AN is disabled (bit 7)
= 0, forced 10BT if AN is disabled (bit 7)
= 1, forced full duplex if (1) AN is disabled or (2)
AN is enabled but failed.
= 0, forced half duplex if (1) AN is disabled or (2)
AN is enabled but failed.
= 1, advertise flow control (pause) capability
= 0, suppress flow control (pause) capability from
transmission to link partner
= 1, advertise 100BT full duplex capability
= 0, suppress 100BT full duplex capability from
transmission to link partner
= 1, advertise 100BT half duplex capability
= 0, suppress 100BT half duplex capability from
transmission to link partner
= 1, advertise 10BT full duplex capability
= 0, suppress 10BT full duplex capability from
transmission to link partner
= 1, advertise 10BT half duplex capability
= 0, suppress 10BT half duplex capability from
