181dc4875b Update iflib to support more NIC designs
- Move group task queue into kern/subr_gtaskqueue.c
- Change intr_enable to return an int so it can be detected if it's not
  implemented
- Allow different TX/RX queues per set to be different sizes
- Don't split up TX mbufs before transmit
- Allow a completion queue for TX as well as RX
- Pass the RX budget to isc_rxd_available() to allow an earlier return
  and avoid multiple calls

596f2a146d Import the 'iflib' API library for network drivers. From the author:
"iflib is a library to eliminate the need for frequently duplicated device
independent logic propagated (poorly) across many network drivers."

Participation is purely optional.  The IFLIB kernel config option is
provided for drivers that want to transition between legacy and iflib
modes of operation.  ixl and ixgbe driver conversions will be committed
shortly.  We hope to see participation from the Broadcom and maybe
Chelsio drivers in the near future.
