Similar with commit 72f6d71e ("vxlan: add ttl inherit support"),
currently ttl == 0 means "use whatever default value" on geneve instead
of inherit inner ttl. To respect compatibility with old behavior, let's
add a new IFLA_GENEVE_TTL_INHERIT for geneve ttl inherit support.

This patch makes sure that ports with such PHYs are configured correctly

====================
Preparing for phylib linkmodes

phylib currently makes us of a u32 bitmap for advertising, supported,
and link partner capabilities. For a long time, this has been
sufficient, for devices up to 1Gbps. With more MAC/PHY combinations
now supporting speeds greater than 1Gbps, we have run out of
bits. There is the need to replace this u32 with an
__ETHTOOL_DECLARE_LINK_MODE_MASK, which makes use of linux's generic
bitmaps.

This patchset does some of the work preparing for this change. A few
cleanups are applied to PHY drivers. Some MAC drivers directly access
members of phydev which are going to change type. These patches adds
some helpers and swaps MAC drivers to use them, mostly dealing with
Pause configuration.
