====================
SFP/phylink fixes

Here are four phylink fixes:
- the "options" is a big-endian value, we must test the bits taking the
  endian-ness into account.
- improve the handling of RX_LOS polarity, taking no RX_LOS polarity
  bits set to mean there is no RX_LOS functionality provided.
- do not report modules that require the address mode switching as
  supporting SFF8472.
- ensure that the mac_link_down() function is called when phylink_stop()
  is called.
