src: add support to add flowtables
This patch allows you to create flowtable: # nft add table x # nft add flowtable x m { hook ingress priority 10\; devices = { eth0, wlan0 }\; } You have to specify hook and priority. So far, only the ingress hook is supported. The priority represents where this flowtable is placed in the ingress hook, which is registered to the devices that the user specifies. You can also use the 'create' command instead to bail out in case that there is an existing flowtable with this name. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
