Bug#561851: mii-tool: Reports Half Duplex for Full Duplex on gigabit

[Kurt Roeckx]

Package: net-tools
Version: 1.60-22
Severity: important

It seems that for gigabit links, half and full duplex are
switched.

dmesg shows:
[   91.259774] tg3: eth0: Link is up at 1000 Mbps, full duplex.
[   91.259778] tg3: eth0: Flow control is on for TX and on for RX.

mii-tool -v:
eth0: negotiated 1000baseT-HD flow-control, link ok
  product info: vendor 00:08:18, model 26 rev 2
  basic mode:   autonegotiation enabled
  basic status: autonegotiation complete, link ok
  capabilities: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control
  link partner: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD

ethtool:
        Speed: 1000Mb/s
        Duplex: Full

Also notice how for "1000baseT" it first reports HD then FD while
for all others it does it the other way around.
