My machine has the following em(4) device and it has a autoneg
problem.  When I was using 8-stable kernel at 2010/11/01, it has no
problem.  But I update to 8-stable at 2010/12/01, the kernel is only
linked up as 10M.


em0 at pci0:0:25:0:    class=0x020000 card=0x13d510cf chip=0x104a8086 rev=0x02 hdr=0x00
     vendor     = 'Intel Corporation'
     device     = '82566DM Gigabit Network Connection'
     class      = network
     subclass   = ethernet
