Implement get_pauseparam() and set_pauseparam() ethtool operations for
Sparx5 ports. This allows users to query and configure IEEE 802.3x
pause frame settings via:
ethtool -a ethX
ethtool -A ethX rx on|off tx on|off autoneg on|off
The driver delegates pause parameter handling to phylink through
phylink_ethtool_get_pauseparam() and phylink_ethtool_set_pauseparam().
The underlying configuration of pause frame generation and reception is
already implemented in the driver; this patch only wires it up to the
standard ethtool interface, making the feature accessible to userspace.
