fxp(4) and Intel 82801GB NIC

[Sergey Solyanik]

Hello!

I have a problem with my -STABLE, fxp(4) doesn't detect available media
  in the Intel 82801GB onboard NIC. It shows that:

solik at solik$ ifconfig fxp1
fxp1: flags=9943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,LINK0,MULTICAST>
mtu 1500
         options=8<VLAN_MTU>
         inet 192.168.250.1 netmask 0xffffff00 broadcast 192.168.250.255
         ether 00:14:85:1a:fc:d3
         media: Ethernet manual

solik at solik$ ifconfig -m fxp1
fxp1: flags=9943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,LINK0,MULTICAST>
mtu 1500
         options=8<VLAN_MTU>
         capabilities=8<VLAN_MTU>
         inet 192.168.250.1 netmask 0xffffff00 broadcast 192.168.250.255
         ether 00:14:85:1a:fc:d3
         media: Ethernet manual
         supported media:
                 media manual

The NIC working (100M/Full) when plugged in switch (Cisco 2950), but
doesn't when connected with another one with crossover cable, or to the
wireless AP (D-Link DWL-2100AP) which do autodetection of speed MDI-X/MDI.
The link continually flapping up and down.
Running Windows XP I can manually select 100M/Full media to link up. But
I can't do that with FreeBSD.

Here is the part of pciconf -lv output:
[...]
fxp1 at pci2:8:0:  class=0x020000 card=0xe0141631 chip=0x27dc8086 rev=0x01
hdr=0x00
     vendor   = 'Intel Corporation'
     device   = '82801GB I/O Controller Hub LAN'
     class    = network
     subclass = ethernet

Please help me to fix it. I will test patches.
Thanks!
