[PATCH net-next v4 08/13] net: phy: phy_device: Use link_capabilities lookup for PHY aneg config
From: Maxime Chevallier
Date: Mon Mar 03 2025 - 04:05:08 EST
When configuring PHY advertising with autoneg disabled, we lookd for an
exact linkmode to advertise and configure for the requested Speed and
Duplex, specially at or over 1G.
Using phy_caps_lookup allows us to build a list of the supported
linkmodes at that speed that we can advertise instead of the first mode
that matches.
