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

[Andrew Lunn]

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.

[PATCH 1/8] net: usb: r8152: Use linkmode helpers for EEE

[Andrew Lunn]

Make use of the existing linkmode helpers for converting PHY EEE
register values into links modes, now that ethtool_keee uses link
modes, rather than u32 values.

Rework determining if EEE is active to make is similar as to how
phylib decides, and make use of a phylib helper to validate if EEE is
valid in for the current link mode. This then requires that PHYLIB is
selected.

[PATCH 4/8] net: ethernet: ixgbe: Convert EEE to use linkmodes

[Andrew Lunn]

Convert the tables to make use of ETHTOOL link mode bits, rather than
the old u32 SUPPORTED speeds. Make use of the linkmode helps to set
bits and compare linkmodes. As a result, the _u32 members of keee are
no longer used, a step towards removing them.

[PATCH 5/8] net: intel: i40e/igc: Remove setting Autoneg in EEE capabilities

[Andrew Lunn]

Energy Efficient Ethernet should always be negotiated with the link
peer. Don't include SUPPORTED_Autoneg in the results of get_eee() for
supported, advertised or lp_advertised, since it is
assumed. Additionally, ethtool(1) ignores the set bit, and no other
driver sets this.

Probably a typo, I think it should be ETHTOOL_LINK_MODE_1000baseT_Full_BIT
here :)
