amd64/119047: Not correct working RealTek 8168/8111B PCIe Gigabit Ethernet

[Torfinn Ingolfsen]

Hmm, this sounds kind of like the problem I have with my Asus M2A-VM HDMI motherboard. Also running FreeBSD / amd64 (currently 7.0-beta4).
More details below.

Can you see errors with 'netstat -i'? In my case, neither 'netstat -i' nor 'netstat  -m' reports any signs of trouble.

My problem is that ssh connections _to_ the machine closes unexpectedly with "bad packet length" or somesuch.
Any ssh connections _from_ the machine seems to be unaffected.

What does 'pciconf -lv | grep -B 4 network' show?
On my Asus M2A-VM HDMI motherboard I get this:
tingo at kg-vm$ pciconf -lv | grep -B 4 network
    subclass   = VGA
re0 at pci0:2:0:0: class=0x020000 card=0x81aa1043 chip=0x816810ec rev=0x01 hdr=0x00
    vendor     = 'Realtek Semiconductor'
    device     = 'RTL8168/8111 PCI-E Gigabit Ethernet NIC'
    class      = network

Hmm, ethernet is probably better:
tingo at kg-vm$ pciconf -lv | grep -B 4 ethernet
re0 at pci0:2:0:0: class=0x020000 card=0x81aa1043 chip=0x816810ec rev=0x01 hdr=0x00
    vendor     = 'Realtek Semiconductor'
    device     = 'RTL8168/8111 PCI-E Gigabit Ethernet NIC'
    class      = network
    subclass   = ethernet

The machine is running 7.0-beta4:
tingo at kg-vm$ uname -a
FreeBSD kg-vm.kg4.no 7.0-BETA4 FreeBSD 7.0-BETA4 #0: Sun Dec  2 16:34:41 UTC 2007     root at myers.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64
