  Log:
  Rework the transmit register handling. In em_encap() store index of
  the EOP descriptor in the first descriptor of the packet. And then
  in em_txeof() search for DD bits set only in the EOP descriptors,
  embedding the cleanup of all packet's descriptors into inner loop.
  
  This change is important for future chips, where DD bit is going
  to be set only on the EOP descriptors.
