parentnet: phy: simplify genphy_config_advert by using the linkmode_adv_to_xxx_t functions (diff)
net: phy: prepare phylib to deal with PHY's extending Clause 22
The integrated PHY in 2.5Gbps chip RTL8125 is the first (known to me) PHY that uses standard Clause 22 for all modes up to 1Gbps and adds 2.5Gbps control using vendor-specific registers. To use phylib for the standard part little extensions are needed: - Move most of genphy_config_aneg to a new function __genphy_config_aneg that takes a parameter whether restarting auto-negotiation is needed (depending on whether content of vendor-specific advertisement register changed). - Don't clear phydev->lp_advertising in genphy_read_status so that we can set non-C22 mode flags before. Basically both changes mimic the behavior of the equivalent Clause 45 functions. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
