extensions: libxt_cpu: Add translation to nft
Add translation for module cpu to nftables. Examples: $ sudo iptables-translate -A INPUT -p tcp --dport 80 -m cpu --cpu 0 -j ACCEPT nft add rule ip filter INPUT tcp dport 80 cpu 0 counter accept $ sudo iptables-translate -A INPUT -p tcp --dport 80 -m cpu ! --cpu 1 -j ACCEPT nft add rule ip filter INPUT tcp dport 80 cpu != 1 counter accept Signed-off-by: Shivani Bhardwaj <shivanib134@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
