the mbuf for obtaining the fib index - check that a cached flow corresponds to the same fib index as the packet for which we are doing the lookup - at interface detach time flush any flows referencing stale rtentrys associated with the interface that is going away (fixes reported panics) - reduce the time between cleans in case the cleaner is running at the time the eventhandler is called and the wakeup is missed less time will elapse before the eventhandler returns - separate per-vnet initialization from global initialization (pointed out by jeli@) Reviewed by: sam@ Approved by: re@
