I'll submit a follow-up RFC series as basis for further discussion.
So far only 32bit legacy bitmaps are passed to userspace. This makes it impossible to manage EEE linkmodes beyond bit 32, e.g. manage EEE for 2500BaseT and 5000BaseT. This series adds support for passing full linkmode bitmaps between kernel and userspace. Fortunately the netlink-based part of ethtool is quite smart and no changes are needed in ethtool. However this applies to the netlink interface only, the ioctl interface for now remains restricted to legacy bitmaps. Next step will be adding support for the c45 EEE2 standard registers (3.21, 7.62, 7.63) to the genphy_c45 functions dealing with EEE. I have a follow-up series for this ready to be submitted.
