[PATCH net-next v4 0/6] ethtool: switch EEE netlink interface to use EEE linkmode bitmaps

[Heiner Kallweit <hkallweit1@gmail.com>]

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.

v2:
- now as RFC
- adopt suggestion from Andrew to start with struct ethtool_keee
  being an identical copy of ethtool_eee, and switch all users
v3:
- switch from RFC to net-next
- add patch 4, and reuse old names in patch 5
- rebase patch 1
v4:
- fix missing replacement in patch 4

Heiner Kallweit (6):
  ethtool: replace struct ethtool_eee with a new struct ethtool_keee on
    kernel side
  ethtool: switch back from ethtool_keee to ethtool_eee for ioctl
  ethtool: adjust struct ethtool_keee to kernel needs
  ethtool: add suffix _u32 to legacy bitmap members of struct
    ethtool_keee
  ethtool: add linkmode bitmap support to struct ethtool_keee
  net: phy: c45: change genphy_c45_ethtool_[get|set]_eee to use EEE
    linkmode bitmaps
