Good luck in getting any help.  bge0 has been going DOWN/UP for
about 2 months.  I've managed to get around the problem by adding

net.inet.tcp.sendspace=131072
net.inet.tcp.recvspace=131072
net.inet.tcp.path_mtu_discovery=0
net.inet.udp.recvspace=65536
net.inet.raw.recvspace=16384
hw.pci.enable_msix=0
hw.pci.enable_msi=0
kern.ipc.nmbclusters=50000
kern.timecounter.hardware=ACPI-fast

to /etc/sysctl.conf.

I also adjusted a few hardcoded parameters in if_bge.c and if_bgereg.h.
