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.
