Log:
  Add flow control for all re(4) controllers. re(4) controllers do
  not provide any MAC configuration interface for resolved flow
  control parameters. There is even no register that configures water
  mark which will control generation of pause frames.
  However enabling flow control surely enhanced performance a lot.
