MFC r180176.
  Add basic support for RTL8168C, RTL8168CP, RTL8111C and RTL8111CP.
  ATM Tx/Rx checksum offload is supported but TSO and jumbo frame is
  not yet supported. Because these newer controllers use different
  descriptor formats, a flag RL_FLAG_DESCV2 flag was introduced to
  handle that case in Tx/Rx handler. Also newer controllers seems to
  require to not touch 'enable Tx/Rx bit' in RL_CPLUS_CMD register
  so don't blindly try to set that bits.

  Note, it seems that there is still power-saving related issue where
  driver fails to attach PHY. Rebooting seems to fix that issue but
  number of required reboots varys.

  Many thanks to users that helped during developement. I really
  appreciate their patient and test/feedbacks.
MFC r180177.
  Add a new RTL8169 variant, 8169SB(L)/8110SB(L).
MFC r180178.
  Add RTL8211C(L) support.
  Disable advanced link-down power saving in phy reset.
MFC r180376.
  Disable jumbo frame support for RTL810x fast ethernet controllers.
MFC r180377.
  Add driver support for RTL8102E and RTL8102EL which is the second
  generation of RTL810x PCIe fast ethernet controller. Note, Tx/Rx
  descriptor format is different from that of first generation of
  RTL8101E series. Jumbo frame is not supported for RTL810x
  family.
MFC r179335.
  Add JMicron JMP202/JMP211 PHY driver.
MFC r179336.
  Connect jmphy(4) to the build.
MFC r179337.
  Add driver support for PCIe adapters based on JMicron JMC250
  gigabit ethernet and JMC260 fast ethernet controllers. ATM jme(4)
  supports all hardware features except RSS and multiple Tx/Rx queue.

  In these days most ethernet controller vendors take a ply of
  concealing hardware detailes from open source developers. As
  contrasted with these vendors JMicron provided all necessary
  information needed to write a stable driver during driver writing
  and answered many questions I had. They even helped fixing driver
  bugs with protocol analyzer. Many thanks to JMicron for their
  support of FreeBSD.

Hopefully get the moving of mergeinfo from etc/rc.d/initrandom to etc
right this time
