  r251482:
    Correct setting TX random backoff register. This register is
    implemented as a 10 bits linear feedback shift register so only
    lower 10 bits are valid.
    Because this register is used to initialize random backoff interval
    register only when resolved duplex is half-duplex, it wouldn't have
    caused issues in these days.
  
  r251733:
    Fix a typo introduced in r213280. IFM_OPTIONS macro should see
    current media word.
