Actually, I wrote all 16 pins (0 to 15) in sys/mips/cavium/octeon_gpio.c so I can see quickly which GPIO pin is connected to reset switch.

It takes some time for me to have fully working setup to test it. Now I know it works against anothetr gigabit card (em driver actually) but not against 100baseT switch. No traffic is seen, even broadcast is not there according to tcpdump. 100baseT link is detected correctly, however, as seen in ifconfig output: media: Ethernet autoselect (100baseTX <full-duplex>) and link LED as well (orange vs. green when 1000baseT mode, as described media: Ethernet autoselect (1000baseT <full-duplex,master>) in ifconfig output). > I've been away at BSDcan for about a week, and so my experience is > about 10-15 days old right now.
