adjust_link() is typically called on transitions from link UP to DOWN and DOWN to UP. This may include the initial configuration of the PHY during e.g: phy_connect() and then typically when an event occurs than requires a re-configuration of the MAC: link parameters (speed, status, duplex, pause) changed. > > Not a network expert (yet), so I'm still digging through the code. Thanks. Reading the PHY state machine under drivers/net/phy/phy.c will make this more clear IMHO. -- Florian
