This makes it easier to add another digest algorithm down the road if needed.

This shouldn't violate any stable API policies, as no released kernel has ever had TCA*BPF_DIGEST.
Imho, this and patch 6/8 is not really needed. Should there ever another digest alg be used (doubt it), then you'd need a new nl attribute and fdinfo line anyway to keep existing stuff intact. Nobody made the claim that you can just change this underneath and not respecting abi for existing applications when I read from above that such apps now will get "forced" to notice a change. -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
