With the new addition of the USXGMII link partner ability constants we can now introduce a phylink helper that decodes the USXGMII word and populates the appropriate fields in the phylink_link_state structure based on them.

Add an interface to configure the advertisement for a clause 22 PCS PHY, and set the AN enable flag in the BMCR appropriately. Reviewed-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
Add a way for MAC PCS to have private data while keeping independence from struct phylink_config, which is used for the MAC itself. We need this independence as we will have stand-alone code for PCS that is independent of the MAC. Introduce struct phylink_pcs, which is designed to be embedded in a driver private data structure. This structure does not include a mdio_device as there are PCS implementations such as the Marvell DSA and network drivers where this is not necessary.

With PCS support, how we implement interface reconfiguration (or other major reconfiguration) is not up to the job; we end up reconfiguring the PCS for an interface change while the link could potentially be up. In order to solve this, add two additional MAC methods for major configuration, one to prepare for the change, and one to finish the change. This allows mvneta and mvpp2 to shutdown what they require prior to the MAC and PCS configuration calls, and then restart as appropriate. This impacts ksettings_set(), which now needs to identify whether the change is a minor tweak to the advertisement masks or whether the interface mode has changed, and call the appropriate function for that update.

Re-code the pause in-band advertisement update in light of the addition of PCS support, so that we perform the minimum required; only the PCS configuration function needs to be called in this case, followed by the request to trigger a restart of negotiation if the programmed advertisement changed. We need to change the pcs_config() signature to pass whether resolved pause should be passed to the MAC for setups such as mvneta and mvpp2 where doing so overrides the MAC manual flow controls.
