The power state is later in the report.  The device should be in state
D0 (full power) rather than D1, D2 or D3 (all mean powered down, perhaps
in Wake-On-LAN mode).

OK, this is normal, although there is no link beat report.

Hmmm, this is reporting the ID of an internal transceiver on a 82559
chip, but there is not additional info.  The only non-zero count is a
single false carrier error.

Hmmm, no indication of link beat at all.  Try running
  mii-diag --watch eth0

And plugging/replugging the cable to see if there is at least a
transient indication of link beat.
