Ethernet Driver Features in 6.12

 Posted on November 18, 2024

A report of features and offloads implemented by ethernet drivers in Linux kernel 6.12.

The content in this report is generated by a crude script that:

  • greps for occurrences of e.g. TC_SETUP_*
  • collates occurrences by driver directory
  • generates a feature matrix with a row per driver directory

Note that the results may not be a 1:1 mapping to actual drivers.
