[net-next,v6,00/12] Convert LAN78xx to PHYLINK

Message

Oleksij Rempel April 10, 2025, 11:52 a.m. UTC

This patch series refactors the LAN78xx USB Ethernet driver to use the
PHYLINK framework for MAC and PHY management.

In the process, various improvements were made to structure the code and
separate concerns such as:
- Refactoring PHY detection and MAC-side interface setup
- Consolidating USB and flow control configuration into helpers
- Dropping legacy EEE and pause handling in favor of PHYLINK equivalents
- Simplifying the suspend/resume flow with proper phylink_suspend/resume
- Removing unused fields and outdated workarounds

changes v6:
- Move unrelated logic out of the main PHYLINK conversion patch:
  - EEE handling, USB config, flow control, LED config, etc., now split
    into separate commits
- Remove obsolete members from struct lan78xx_net earlier, in the patch
  where they're no longer needed

changes v5:
- merge ethtool pause configuration patch with PHYlink patch
- merge some other small cleanup to a single patch

changes v4:
- split "Improve error handling in PHY initialization" patch and move
  some parts before PHYlink porting to address some of compile warning
  as early as possible.
- add cleanup patch to remove unused struct members
