New Revision: 217766
URL: http://svn.freebsd.org/changeset/base/217766

Log:
  Apply TX interrupt moderation to all RTL810xE PCIe Fast Ethernet
  controllers. Experimentation with RTL8102E, RTL8103E and RTL8105E
  showed dramatic decrement of TX completion interrupts under high TX
  load(e.g.  from 147k interrupts/second to 10k interrupts/second)
  With this change, TX interrupt moderation is applied to all
  controllers except RTL8139C+.
