src: add set netlink message to the batch
This patch moves the netlink set messages to the batch that contains the rules. This helps to speed up rule-set restoration time by changing the operational. To achieve this, an internal set ID which is unique to the batch is allocated as suggested by Patrick. To retain backward compatibility, nft initially guesses if the kernel supports set in batches. Otherwise, it falls back to the previous (slowier) operational. Signed-off-by: Pablo Neira Ayuso <>
