- Subject: [PATCH] net: phylink: add legacy_pre_march2020 indicator
- Add a boolean to phylink_config to indicate whether a driver has not
- been updated for the changes in commit 7cceb599d15d ("net: phylink:
- avoid mac_config calls"), and thus are reliant on the old behaviour.
- We were currently keying the phylink behaviour on the presence of a
- PCS, but this is sub-optimal for modern drivers that may not have a
- PCS.
- This commit merely introduces the new flag, but does not add any use,
- since we need all legacy drivers to set this flag before it can be
- used. Once these legacy drivers have been updated, we can remove this
- flag.
