    sys/pci              if_vr.c if_vrreg.h 
  Log:
  Improve the if_vr driver ever so slightly.
  
  The 6105M and 6102 does not have the DWORD alignment problem, so
  don't m_defrag() every packet in the transmit path for those.
  
  More stringent usage of tx-descriptor ring and its flags.
  
  Tested on 6102 and 6105M, other chips may also be able to run
  without the m_defrag() but I have neither hardware nor docs to
  find out.
