Hi, The following series changes the phylink interface to allow us to better support split MAC / MAC PCS setups. The fundamental change required for this turns out to be quite simple. Today, mac_config() is used for everything to do with setting the parameters for the MAC, and mac_link_up() is used to inform the MAC driver that the link is now up (and so to allow packet flow.) mac_config() also has had a few implementation issues, with folk who believe that members such as "speed" and "duplex" are always valid, where "link" gets used inappropriately, etc. With the proposed patches, all this changes subtly - but in a backwards compatible way at this stage. We pass the the full resolved link state (speed, duplex, pause) to mac_link_up(), and it is now guaranteed that these parameters to this function will always be valid (no more SPEED_UNKNOWN or DUPLEX_UNKNOWN here - unless phylink is fed with such things.) Drivers should convert over to using the state in mac_link_up() rather than configuring the speed, duplex and pause in the mac_config() method. The patch series includes a number of MAC drivers which I've thought have been easy targets - I've left the remainder as I think they need maintainer input. However, *all* drivers will need conversion for future phylink development.
