Where would be this pointer allocated? TX response is not the same
flow as TX where we keep it on the stack. It's will be very error
prone to be outside tx_status. From concept perspective you already
have all transimission information in that structure.
For iwlwifi I actually need only u32 value but I was looking for
something more general even it's a little pain.

You don't need to allocate it, it can just point to the rate array you
have registered, no? Rates information is static after all. Or do it like
rx status where we pass the index into the rate array.

I prefer not. This is not just plcp rate there is also MCS flags that
have to passed. With all combinations the array will be huge.
