  SVN rev 182416 on 2008-08-28 22:28:28Z by jfv
  
  Update to igb driver:
  
          - changes in support of the VLAN filter fix to 126850
          - removal of a bunch of legacy code that was cruft, if not
            possibly harmful.
          - removal of POLLING from this driver, with multiqueue and
             MSIX it just makes no sense here.
          - Fix an LRO bug that I've been working on internally, intermittent
            panics under stress, the problem was releasing the RX ring lock
            before the LRO flushing.
          - Following the above fix I now enable LRO by default
          - For performance reasons increase the default number of RX queues
            to 4.
          - Add AIM - "Adaptive Interrupt Moderation", a fancy way of saying
            that the EITR value is dynamically changed based on the size of
            packets in the last interrupt interval.
  
          - Much goodness to try, enjoy!!
