iwn rtsol on stable/10 with merge from head

[Curtis Villamizar]

rtsol is not working for my kernel build with iwn but everything else
works.

I'm running a very recent stable/10 (kernel is 262621) upgraded to
pick up iwn stuff from head:

  svn merge \
    https://svn0.us-east.freebsd.org/base/head/sys/dev/iwn \
    dev/iwn
  svn merge \
    https://svn0.us-east.freebsd.org/base/head/sys/modules/iwnfw \
    modules/iwnfw
  svn merge
    https://svn0.us-east.freebsd.org/base/head/sys/contrib/dev/iwn \
    contrib/dev/iwn

That was to get the Centrino 2000 support from the head branch.

That works.

  iwn0: <Intel(R) Centrino(R) Wireless-N 2200 BGN>
     mem 0xf1c00000-0xf1c01fff irq 17 at device 0.0 on pci3

Everything works as far as I can tell except rtsol.

  # rtsold -f -d -D wlan0
  checking if wlan0 is ready...
  wlan0 does not accept Router Advertisement.
  set timer for wlan0 to 1s
  New timer is 1s
  timer expiration on wlan0, state = 3
  checking if wlan0 is ready...
  wlan0 does not accept Router Advertisement.
  set timer for wlan0 to 1s
  New timer is 1s
  timer expiration on wlan0, state = 3
  checking if wlan0 is ready...
  wlan0 does not accept Router Advertisement.
  set timer for wlan0 to 1s

  [ ... etc ... ]

If I use rtsold -a it sees wlan0 as not ready and doesn't try to use
it but then it receives occasional RA anyway but ignores them because
it sees wlan0 as not ready.

If I ifconfig inet6 ... alias I get an IPv6 address configured and
manually add a default route, then everything is fine.  This
workaround is OK for home but is not practical for roaming about (like
going to IETF) if I want IPv6 to work.

Does anyone know why rtsold isn't seeing wlan0 as ready?  Is there any
info I could provide?  How likely is it that will a kernel built from
head this would just go away and rtsold would just work.

btw- headed for IETF so I'll have a chance to test iwn in a very busy
environment and would be willing to help if anyone wants to do that
sort of debugging.  [I have a usb wlan (run0) as a fallback]
