>Description:

I'm having big problems with the bnx(4) interface on NetBSD 4.0_RC4, the
interface will not autoconfigure itself and I don't get the default route
from the RA message. If I physically replace the bnx(4) interface with e.g.
wm(4) everything works just fine.

Here's part of my dmesg:

bnx0 at pci14 dev 0 function 0: Broadcom NetXtreme II BCM5708 1000Base-T
bnx0: Ethernet address xx:xx:xx:xx:xx:xx

>How-To-Repeat:

- try using a host with bnx(4) interface (e.g. Dell PowerEdge 29x0)
- set ip6mode=autohost in /etc/rc.conf and reboot
- run "netstat -rnf inet6 | grep default" and notice that you don't have
  the default router configured even though your router is sending RAs
- run "rtsol bnx0" and notice you still don't get the default router configured
- on another terminal, run "tcpdump -ni bnx0" to set the interface into
  promiscuous mode
- re-run "rtsol bnx0" and notice you have now the default router configured
