Subject: netfilter: nf_tables: increase maximum devices number per flowtable
Patch-mainline: v5.5-rc1
Git-commit: cb662ac6711f7135618526221498ebfae155531a
References: bsc#1176447

Rise the maximum limit of devices per flowtable up to 256. Rename
NFT_FLOWTABLE_DEVICE_MAX to NFT_NETDEVICE_MAX in preparation to reuse
the netdev hook parser for ingress basechain.
