[PATCH RFC net-next 03/13] net: phylink: rearrange resolve mac_config() call

[Russell King]

Use a boolean to indicate whether mac_config() should be called during
a resolution. This allows resolution to have a single location where
mac_config() will be called, which will allow us to make decisions
about how and what we do.
