[PATCH net v4 0/3] Fix PHY handle no longer parsing

From: Michael Sit Wei Hong
Date: Thu Mar 30 2023 - 04:40:59 EST


After the fixed link support was introduced, it is observed that PHY
no longer attach to the MAC properly. So we introduce a helper
function to determine if the MAC should expect to connect to a PHY
and proceed accordingly.

Michael Sit Wei Hong (3):
net: phylink: add phylink_expects_phy() method
net: stmmac: check if MAC needs to attach to a PHY
net: stmmac: remove redundant fixup to support fixed-link mode

v2: Initialize fwnode before using the variable
v3: Introduced phylink_expects_phy() method as suggested by Russell King
remove xpcs_an_inband fixup instead of moving the fixed-link check
as suggested by Andrew Lunn
v4: Modify phylink_expects_phy() to check for more complete set of
conditions when no PHY is needed and return false if met.
