Subject: [PATCH net-next v2 0/8] drivers: net: Convert EEE handling to use
 linkmode bitmaps

EEE has until recently been limited to lower speeds due to the use of
the legacy u32 for link speeds. This restriction has been lifted, with
the use of linkmode bitmaps. This patchset convert some MAC drivers
still using the old _u32 to link modes, with the aim of soon being
able to remove the legacy _u32 members in the keee structure.

A couple of Intel drivers do odd things with EEE, setting the autoneg
bit. It is unclear why, no other driver does, ethtool does not display
it, and EEE is always negotiated. One patch in this series deletes
this code. Comments on why its actually useful and should be kept are
gratefully received.
