o RTL8169S/8110S integrated PHY and RTL8211B are gigabit PHYs so set
  mii_anegticks to MII_ANEGTICKS_GIGE and use it. Previously it used
  to MII_ANEGTICKS which may not be enough to wait before retrying
  autonegotiation process at 1000bps.
o Reset autonegotation timer if media option is not IFM_AUTO or we
  got a valid link.
o Announce link loss right after it happends.
o Autonegiation is retried every mii_anegticks seconds.
o Report link state changes right after setting autonegotiation.
