>Description:

	rtsol is called in the boot process before the ipfw is configured.
	This results in the solicitations being blocked.  As a
	result it can take up to 10 minute (the default router
	advertisement interval) for the interfaces to autoconfigure.
	
>How-To-Repeat:

>Fix:

	Possible solutions:
	* Reorder the boot process to config ipfw before the ipv6 interfaces
	  are configure.
	* Delay the calling of rtsol until after any firewall is configured.
	* Call rtsol a second time after the firewall is configured.
	* Add minimal rulesets to enable router solicitations to be
	  send route advertisements to be received.
