    net: netcp: ale: update to support unknown vlan controls for NU switch · ca47130a
    Karicheri, Muralidharan authored
    In NU Ethernet switch used on some of the Keystone SoCs, there is
    separate UNKNOWNVLAN register for membership, unreg mcast flood, reg
    mcast flood and force untag egress bits in ALE. So control for these
    fields require different address offset, shift and size of field.
    As this ALE has the same version number as ALE in CPSW found on other
    SoCs, customization based on version number is not possible. So
    use a configuration parameter, nu_switch_ale, to identify the ALE
    ALE found in NU Switch. Different treatment is needed for NU Switch
    ALE due to difference in the ale table bits, separate unknown vlan
    registers etc. The register information available in ale_controls,
    needs to be updated to support the netcp NU switch h/w. So it is not
    constant array any more since it needs to be updated based
    on ALE type. The header of the file is also updated to indicate it
    supports N port switch ALE, not just 3 port. The version mask is
    3 bits in NU Switch ALE vs 8 bits on other ALE types.
    
    While at it, change the debug print to info print so that ALE
    version gets displayed in boot log.
