Merge branch 'phylib-fixed-speed-1G'

Russell King says:

====================
net: phylib: fix fixed-speed >= 1G

This is v2 of the patch (now patches) adding support for ethtool
!autoneg while respecting the requirements of IEEE 802.3.

v2 fixes the build errors in the previous patch by first constifying
the "advertisement" argument to the linkmode functions that only
read from this pointer. It also fixes the incorrectly named
linkmode_set function.
