New Revision: 208508
URL: http://svn.freebsd.org/changeset/base/208508

Log:
  MFp4 @178283:
  
  Improve IPsec flow distribution for better netisr parallelism.
  Instead of using the pointer that would have the last bits masked in a %
  statement in netisr_select_cpuid() to select the queue, use the SPI.
