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.  10 & 100 Mb use a
single pair in each direction.  Gb uses all 4 pairs in both directions. 
However, it the connection only worked in 1 direction, I wouldn't expect
the connection to work at all, as Ethernet tests for connectivity,
before enabling the link.  An intermittent or poor connection might
allow things to work a bit, but not enough to work properly.
