>Description:
	after splraiseipl change, softintr_establish() expects SI_* argument,
	while it's actually IPL_*.
	it happens to work because IPL_SOFT == SI_SOFTNET.

	(it's impossible for softintr_establish to get SI_* from given IPL_*,
	because all of IPL_SOFT* are the same value.)
>How-To-Repeat:
	code inspection.
>Fix:
	one of the followings?

	- coalesce softintr queues into a single queue.
	- change one of splraiseipl or softintr_establish, so that
	  they don't share IPL_ constants.
	- make IPL_SOFT* different each other, and have a simple conversion
	  in both of splraiseipl and softintr_establish.
