Modified Files:
src/sys/net: pktqueue.c
Log Message:
In pktq_flush():
- Run a dummy softint at IPL_SOFTNET on all CPUs to ensure that the
ISR for this pktqueue is not running (addresses a pre-existing XXX).
- Hold the barrier lock around the critical section to ensure that
implicit pktq_barrier() calls via pktq_ifdetach() are held off during
the critical section.
- Ensure the critical section completes in minimal time by not freeing
memory during the critical section; instead, just build a list of the
packets pulled out of the per-CPU queues and free them after the critical
section is over.
