svn commit: r213280 - head/sys/dev/bge

New Revision: 213280
URL: http://svn.freebsd.org/changeset/base/213280

Log:
  After r207391, brgphy(4) passes resolved flow-control settings to
  parent driver. Use that information to configure flow-control.
  One drawback is there is no way to disable flow-control as we still
  don't have proper way to not advertise RX/TX pause capability to
  link partner. But I don't think it would cause severe problems and
  users can selectively disable flow-control in switch port.
