The pause quanta value to be inserted into pause
control packets.
The upper 42 bits of the MAC source addresses. The
least significant 6 bits are hardwired per port.
Asserting this bit disables the SGMII termination
compensation function for all channels. For normal
operation, this bit is deasserted.
Asserting this bit causes the SGMII autonegotiation
process to be sped up. For normal operation, this bit
is deasserted. This bit has no effect on the autonego-
tiation process executed by the external PHY on the
network.
This bit is asserted to enable the PRBS test mode for
all SGMII channels. The PRBS test runs for as long
as this bit is asserted. For normal operation, this bit is
deasserted.
