With 1000baseTX cards, establishing a link between two ports requires
that one port be configured as a master and the other a slave. With
autonegotiation, the master/slave settings will be chosen automatically.
However when manually selecting the link state, it is necessary to
force one side of the link to be a master and the other a slave. The
.Nm
driver configures the ports as slaves by default. Setting the
.Ar link0
flag with
.Xr ifconfig 8
