[PATCH net-next v7 7/9] net: phy: c45: migrate to genphy_c45_write_eee_adv()

From: Oleksij Rempel
Date: Thu Feb 09 2023 - 04:51:53 EST


Migrate from genphy_config_eee_advert() to genphy_c45_write_eee_adv().

It should work as before except write operation to the EEE adv registers
will be done only if some EEE abilities was detected.

If some driver will have a regression, related driver should provide own
.get_features callback. See micrel.c:ksz9477_get_features() as example.
