Thanks for the info. Let me add Maxime as author of the fix.
I think we talk about his one "net: phy: marvell10g:
Fix Multi-G advertisement to only advertise 10G" and we talk
about net-next.

IMO the proper way to fix this is removing the unsupported
modes from phydev->advertising in config_init.
Then mv3310_config_aneg doesn't have to be touched.

A similar exercise I did here:
0974f1f03b07 ("net: phy: aquantia: remove false 5G and 10G speed ability for AQCS109")
