You should probably send patches as RFC if you have things like that.

Maybe so, but does anything _else_ MLO related still work? Surely it
cannot, given you just unconditionally made it no longer have a link ID
... And indeed most of the EHT hwsim tests no longer pass, and even
crash the kernel.

Since you clearly were running hwsim tests, please run the existing ones
too :)

Also, I suspect that https://lore.kernel.org/linux-
wireless/20250630084119.3583593-1-quic_sarishar@quicinc.com/ might go
some way towards fixing this as well?
