Merge branch '100base-Fx-link-modes'

Dan Murphy says:

====================
100base Fx link modes

As per patch https://lore.kernel.org/patchwork/patch/1300241/ the link
modes for 100base FX full and half duplex modes did not exist.  Adding
these link modes to the core and ethtool allow devices like the
DP83822, DP83869 and Broadcomm PHYs to properly advertise the correct
mode for Fiber 100Mbps.

Corresponding user land ethtool patches are available but rely on
these patches to be applied first.
