- New 82580 devices supported
- Fixes from John Baldwin: vlan shadow tables made per/interface,
  make vlan hw setup only happen when capability enabled, and
  finally, make a tuneable interrupt rate. Thanks John!
- Tweaked watchdog handling to avoid any false positives, now
  detection is in the TX clean path, with only the final check
  and init happening in the local timer.
- limit queues to 8 for all devices, with 82576 or 82580 on
  larger machines it can get greater than this, and it seems
  mostly a resource waste to do so. Even 8 might be high but
  it can be manually reduced.
- use 2k, 4k and now 9k clusters based on the MTU size.
- rework the igb_refresh_mbuf() code, its important to
  make sure the descriptor is rewritten even when reusing
  mbufs since writeback clobbers things.

MFC: in a few days, this delta needs to get to 8.2
