I took a look, I don't immediately see the concern.

The new entry is at the end of the memory structure.
The call back is internal and hidden behind the symbol rte_devargs_layers_parse.

So will only be trigger by a rte_devargs_layers_parse of the same version of DPDK that introduce the new callback.

Should be fine?
