hash: generate a random seed if seed option is empty
Typing the "nft add rule x y ct mark set jhash ip saddr mod 2" will not generate a random seed, instead, the seed will always be zero. So if seed option is empty, we shoulde not set the NFTA_HASH_SEED attribute, then a random seed will be generated in the kernel. Signed-off-by: Liping Zhang <> Signed-off-by: Pablo Neira Ayuso <>
