That would be: 1f069de63602 ethtool: add linkmode bitmap support to struct ethtool_keee 1d756ff13da6 ethtool: add suffix _u32 to legacy bitmap members of struct ethtool_keee 285cc15cc555 ethtool: adjust struct ethtool_keee to kernel needs 0b3100bc8fa7 ethtool: switch back from ethtool_keee to ethtool_eee for ioctl d80a52335374 ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side > One small nit: convert*s* Thanks. Andrew
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.
