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!!
