I am using nfe on 6.3 amd63 system with the code from here:
http://www.f.csce.kyushu-u.ac.jp/~shigeaki/software/freebsd-nfe.html
Everything is OK except for one small, but annoying problem. Sometimes
when my system hangs and I have to use reset button, nfe stops working
after reboot. ifconfig shows proper status and medium, there are no
kernel error/debug messages, on the surface everything seems good. But
if I try to ping a machine connected to the same switch I get "host
down" responses. So, no network at all. Unloading and reloading if_nfe
module doesn't help, various ifconfig re-configurations do not help too.
Although, if I do power off and then boot, everything is perfect again.
Until a couple of weeks ago I used 6.2 amd64 and nve (patched to
recognize pci id of this card) and I never had such a problem.
To un-enlightened me it seems like some resetting/re-initialization of
the card is not done properly by nfe.
Additional info.

P.S. as always with network issues, I understand that it may be not so
simple, e.g. some interaction between the card and the switch, etc.

After applying attached patch and let me know the output of
"devid : xxx, revid : xxx, pwr = xxx". It would be even better
if you can show me the above message for working/non-working case.

If I gracefully reboot the machine or power down and then up, then everything is OK. But if I press "reset" button and boot up, the nfe interface is "dead". BTW, I kept the line for printing devid/revid/pwr and output is the same in all cases. -- Andriy Gapon
