Robert Watson 3be4cb0b4a Merge Neterion if_nxge driver version 2.0.9.11230 with the following 
changes:

  01 -  Enhanced LRO:
  LRO feature is extended to support multi-buffer mode. Previously,
  Ethernet frames received in contiguous buffers were offloaded.
  Now, frames received in multiple non-contiguous buffers can be
  offloaded, as well. The driver now supports LRO for jumbo frames.

  02 - Locks Optimization:
  The driver code was re-organized to limit the use of locks.
  Moreover, lock contention was reduced by replacing wait locks
  with try locks.

  03 - Code Optimization:
  The driver code was re-factored  to eliminate some memcpy
  operations.  Fast path loops were optimized.

  04 - Tag Creations:
  Physical Buffer Tags are now optimized based upon frame size.
  For better performance, Physical Memory Maps are now re-used.

  05 - Configuration:
  Features such as TSO, LRO, and Interrupt Mode can be configured
  either at load or at run time. Rx buffer mode (mode 1 or mode 2)
  can be configured at load time through kenv.

  06 - Driver Statistics:
  Run time statistics are enhanced to provide better visibility
  into the driver performance.

  07 - Bug Fixes:
  The driver contains fixes for the problems discovered and
  reported since last submission.

  08 - MSI support:
  Added Message Signaled Interrupt feature which currently uses 1
  message.

  09  Removed feature:
  Rx 3 buffer mode feature has been removed. Driver now supports 1,
  2 and 5 buffer modes of which 2 and 5 buffer modes can be used
  for header separation.

  10  Compiler warning:
  Fixed compiler warning when compiled for 32 bit system.
