Therefore I think fxp0/fxp1 are 82550C (on motherboard) and fxp2 is
original 82550. I have several servers with this constellation and saw
SCB timeouts only one time during the last 6 month while debugging with
wireshark:
<kern.info> fwvpn kernel: fxp0: promiscuous mode enabled
<kern.crit> fwvpn kernel: fxp0: Microcode loaded, int_delay: 1000 usec
bundle_max: 6
<kern.crit> fwvpn kernel: fxp0: SCB timeout: 0x80 0x20 0x90 0x1
<kern.crit> fwvpn last message repeated 5 times
