  SVN rev 218903 on 2011-02-21 01:08:13Z by yongari
  
  MFC r217499:
    Implement initial jumbo frame support for RTL8168/8111 C/D/E PCIe
    GbE controllers. It seems these controllers no longer support
    multi-fragmented RX buffers such that driver have to allocate
    physically contiguous buffers.
  
     o Retire RL_FLAG_NOJUMBO flag and introduce RL_FLAG_JUMBOV2 to
       mark controllers that use new jumbo frame scheme.
     o Configure PCIe max read request size to 4096 for standard frames
       and reduce it to 512 for jumbo frames.
     o TSO/checksum offloading is not supported for jumbo frames on
       these controllers. Reflect it to ioctl handler and driver
       initialization.
     o Remove unused rl_stats_no_timeout in softc.
     o Embed a pointer to structure rl_hwrev into softc to keep track
       of controller MTU limitation and remove rl_hwrev in softc since
       that information is available through a pointer to structure
       rl_hwrev.
  
    Special thanks to Realtek for donating sample hardwares which made
    this possible.
