QCA808x does not currently fill in the possible_interfaces. This leads to Phylink not being aware that it supports 2500Base-X as well so in cases where it is connected to a DSA switch like MV88E6393 it will limit that port to phy-mode set in the DTS. That means that if SGMII is used you are limited to 1G only while if 2500Base-X was set you are limited to 2.5G only. Populating the possible_interfaces fixes this, so lets backport the patches from kernel 6.9. This also includes a backport of the Phylink PHY validation series from kernel 6.8 that allows the use of possible_interfaces.

Subject: [PATCH 5/7] net: phylink: pass PHY into phylink_validate_mask()
|
|
|
|
Pass the phy (if any) into phylink_validate_mask() so that we can
|
|
validate each interface with its rate matching setting.
