Daniel Golle ee035de0fd kernel: fix mvneta Ethernet after generic phylink validate
Import patches from Linux v5.16 and v5.17 to get 2500Base-X SFP working
again with mvneta driver after the generic phylink validate backport.

Subject: [PATCH] net: mvneta: use phylink_generic_validate()
Convert mvneta to use phylink_generic_validate() for the bulk of its
validate() implementation. This network adapter has a restriction
that for 802.3z links, autonegotiation must be enabled.
