This patch converts the ips(4) driver to the callout(9) API and adds 
additional locking to remove its use of Giant.  The patch is against HEAD but 
probably applies to 9 and 10 as well.  Please test with INVARIANTS enabled.

http://www.FreeBSD.org/~jhb/patches/ips_callout.patch

Note that this driver is using a deprecated API that will be removed in 11.  
If no one tests updates to this driver then it is not feasible to continue 
maintaining it in the tree.  In that case, it will be removed from HEAD one 
month from today.
