Package: ethtool
Version: 5-1
Severity: normal
Fails to detect the current duplex setting:
img2:~# mii-tool eth0
eth0: 100 Mbit, full duplex, link ok
img2:~# ethtool eth0 | grep -i duplex
Duplex: Half
(mii-tool's output is correct.)
Fails to set the duplex correctly:
img2:~# ethtool -s eth0 duplex full
img2:~# mii-tool eth0
eth0: no autonegotiation, 100baseTx-HD, link ok
img2:~# ethtool eth0 | grep -i duplex
Duplex: Half
Performing an actual transfer of data from this host to another host
reveals that, indeed, the interface is operating at the wrong duplex
setting.
The "ethtool -s eth0 duplex full" test seems to have caused these kernel
messages (for whatever that's worth):
Dec 27 10:45:49 img2 kernel: tg3: eth0: Link is down.
Dec 27 10:45:51 img2 kernel: tg3: eth0: Link is up at 100 Mbps, half duplex.
Dec 27 10:45:51 img2 kernel: tg3: eth0: Flow control is off for TX and off for
RX.
Hardware information:

Here's the full output of ethtool, after I used mii-tool to repair the
duplex setting:
img2:~# ethtool eth0

Bug #440319 is related to this one, but only as background information
about why I was trying to use ethtool at all.
