Commit 3c1bcc8614db ("net: ethernet: Convert phydev advertize and supported from u32 to link mode") updated ethernet drivers to use a linkmode bitmap. It mistakenly dropped a bitwise negation in the tc35815 ethernet driver on a bitmask to set the supported/advertising flags.
Found by Anthony via code inspection, not tested as I do not have the required hardware.
