Can a network connection be unidirectional?

Only at 10/100 Mb.  However, a bad connection might cause the NIC to
think it has a 10/100 connection, instead of Gb.

The fault can be with the NIC or driver too (or even the combination of a NIC
with a particular switch).

I have had cases where the NIC would, at first plugging in of the cable, end up
in a 10 or 100Mbit state. Then, kicking the software with `ethtool eth0 autoneg
on` (autoneg was already on!), just to retrigger negotiation, would switch the
link to the 1000 I was expecting.
