Subject: [PATCH 1/7] net: phylink: keep and use MAC supported_interfaces in
|
|
phylink struct
|
|
|
|
Add in phylink struct a copy of supported_interfaces from phylink_config
|
|
and make use of that instead of relying on phylink_config value.
|
|
|
|
This in preparation for support of PCS handling internally to phylink
|
|
where a PCS can be removed or added after the phylink is created and we
|
|
need both a reference of the supported_interfaces value from
|
|
phylink_config and an internal value that can be updated with the new
|
|
PCS info.
