>Synopsis: Intel 82579LM auto negotiation fails at boot
>Category: amd64 kernel system
>Environment:
System : OpenBSD 5.1
Details : OpenBSD 5.1-current (GENERIC.MP) #227: Thu Mar 22
11:10:40 MDT 2012
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
em(4) describes 82579LM is one of supported chips, but
auto-negotiation fails at boot, always links at 100Mbps on
Thinkpad X220 (4286CTO).
Despite of "sudo ifconfig em0 media" showing 1000BaseT
capability, manually select 'media 1000baseT mediaopt
full-duplex' also 'media 1000baseT' with ifconfig bring no
links at all.
>How-To-Repeat:
Rebooting system.
>Fix:
Following patch fix my problems, auto-negotiation at boot and
"ifconfig media" works as expected. I haven't checked any other
em_pch2lan machines since I don't have any. Tests needed.

Not exactly related with the previous issue, but I found the following
code while I was struggling to fix the problem. What do you think? (I
am just a learner of programming, so I am not sure about this..)
