        src/sys/dev/pci/ixgbe: if_sriov.c ixgbe.c ixgbe.h ixgbe_netbsd.c
            ixgbe_osdep.h ixv.c

Log Message:
Reduce ixgbe's busy loop using with workqueue and kpause.

- Use workqueue instead of softint to make some functions sleepable.
- Use new workqueue and enqueue it in ixgbe_local_timer() and
  ixgbe_recovery_mode_timer() to make them sleepable.
- Make new ixgbe_delay() and use it. This functions sleeps if the time is
  more than equals 1 tick. If it's not, do delay().
