[PATCH net-next v8 7/8] net: fec: Move fec_enet_eee_mode_set() and helper earlier

From: Oleksij Rempel
Date: Fri Mar 01 2024 - 05:02:36 EST


From: Andrew Lunn <andrew@xxxxxxx>

FEC is about to get its EEE code re-written. To allow this, move
fec_enet_eee_mode_set() before fec_enet_adjust_link() which will
need to call it.
