  Log:
  Add support for the 8139C+ chipset. Unlike the other chips in the 8139
  series, the 8139C+ has a descriptor-based DMA mechanism, and its
  performance is actually pretty respectable. Note: the 8139D chip does
  not support C+ mode. Only the 8139C+ and 8169 gigE chips support C+ mode.
  
  Supported features:
  
  - RX and TX checksum offload
  - hardware VLAN tag insertion/extraction
  - TX interrupt moderation using the 8139's on-board timer
  
  Everything should be properly busdma'ed and endian-independent, so
  things should work ok on non-x86 platforms. Unfortunately, my call
  for testers on this code was met with deafening silence, and I don't
  have access to any non-x86 FreeBSD boxes at the moment, so this is
  speculation.
  
  The device detection code has been cleaned up a little as well
  (thanks to Michal Mertl) for the patches.
  
  There are also updates to the rl(4) man page (which I accidentally
  checked in before when I updated the dc(4) man page. Oops.)
  
  Todo: finish support for the 8169 gigabit ethernet chip. This
  mainly requires writing an rlgphy driver to handle the 8169's built-in
  PHY. This will have to wait until I actually get my hands on an 8169
  card for testing though. (I still can't find a source for one in the
  U.S. Suggestions/pointers welcome.)
