Subject: r8169 - it's dead jim
Date: Sat, 23 Nov 2013 12:46:00 -0700	[thread overview]
Message-ID: <529105F8.9030901@nurealm.net> (raw)

Hey

Going from 3.12.0-1-ARCH to 3.12.1-1-ARCH, the r8169 module is having the "link
detect" problem again.

Initially, "ethtool -s <blah> autoneg off" gives "invalid argument".

"sudo mii-tool -R enp22s0" - Reset the MII to its default configuration - will
allow a 10Mb/s half duplex connection, with "autoneg off".

"ethtool -s <blah> autoneg off" then will work, after the "mii-tool -R <blah>".

After some time, Auto-negotiation will spontaneously go on, and a 100Mb/s full
duplex connection will come up, on a 1Gb/s interface.  Subsequent unplugging and
plugging the cable gives a 1Gb/s full duplex connection.

This problem has been recurring for so many years, I hope the solution is
something obvious, perhaps a recent change to the kernel?


Thanks
James
