Series drivers: net: Convert EEE handling to use linkmode bitmaps |

Commit Message

Andrew Lunn Feb. 17, 2024, 6:08 p.m. UTC 
  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.
