This would be rather helpful to me for some stuff that I am currently
working on and was hoping to send to Arnd for inclusion in 6.8:
https://lore.kernel.org/all/20231020-series-uncooked-077b107af3ae@spud/

I'm currently returning a "HW_ERROR" for something that this would fit
the bill for (in mpfs_auto_update_write()). What would the ETA for this
stuff landing via the net tree be?
Since I am not a netdev contributor its hard to tell how controversial
these patches are!

Cheers,
Conor.
