XDP_UMEM_TX_METADATA_LEN is missing after d5e726d9143c ("xsk: Require
XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len"), so that make
sense. Maybe add a fixes tag?

And I don't see mlx5 looking at HWTSTAMP_TX anywhere in the drivers,
so I'm assuming that's why I didn't need HWTSTAMP_TX_ON during my tests..
Which device are you testing against? I do see some hwts_tx_en
checks in the stfmmac at least... Can you add these details to the
commit message and respin?
