The API to the PHY is not very obvious, which is probably why. Rework the API, pushing most of the EEE handling into phylib core, leaving the MAC drivers to just enable/disable support for EEE in there change_link call back. MAC drivers are now expect to indicate to phylib if they support EEE. This will allow future patches to configure the PHY to advertise no EEE link modes when EEE is not supported. The information could also be used to enable SmartEEE if the PHY supports it. With these changes, the uAPI configuration eee_enable becomes a global on/off. tx-lpi must also be enabled before EEE is enabled. This fits the discussion here: https://lore.kernel.org/netdev/af880ce8-a7b8-138e-1ab9-8c89e662eecf@gmail.com/T/ This patchset puts in place all the infrastructure, and converts one MAC driver to the new API. Following patchsets will convert other MAC drivers, extend support into phylink, and when all MAC drivers are converted to the new scheme, clean up some unneeded code. v6: --- Reword different comments. See per patch change comments. v5: -- Rebase against latest netdev-next Use keee instead of eee struct v4 -- Only convert one MAC driver Drop all phylink code Conform to the uAPI discision. v3 -- Rework phylink code to add a new callback.
