Enables the corresponding Ethernet port. When a
port_en bit is false, all activity of the associated Ether-
net port is disabled.
This read-only bit is asserted whenever a good link status
exists for the corresponding SGMII channel. Forcing a
good link status by asserting force_good_link also
causes good_link to be asserted.
This read-only bit is asserted whenever a full duplex sta-
tus exists for the corresponding SGMII channel. Forcing a
full duplex status by asserting force_full_duplex
also causes full_duplex to be asserted.
This bit is asserted to disable the SGMII offset compen-
sation circuitry. For normal operation, this bit is deas-
serted.
Asserting this bit powers down the associated SGMII
interface module. For normal operation, this bit is deas-
serted.
