netfilter: nft_fib: add reduce support
The fib expression stores to a register, so we can't add empty stub. Check that the register that is being written is in fact redundant. In most cases, this is expected to cancel tracking as re-use is unlikely. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
