Subject: [PATCH net-next v1 6/7] net: usb: lan78xx: Transition get/set_pause to phylink

Replace lan78xx_get_pause and lan78xx_set_pause implementations with
phylink-based functions. This transition aligns pause parameter handling
with the phylink API, simplifying the code and improving
maintainability.
