Pablo Neira Ayuso 23cb1fef93 netfilter: nf_tables: bail out early if hardware offload is not supported
[ Upstream commit 3a41c64d9c1185a2f3a184015e2a9b78bfc99c71 ]

If user requests for NFT_CHAIN_HW_OFFLOAD, then check if either device
provides the .ndo_setup_tc interface or there is an indirect flow block
that has been registered. Otherwise, bail out early from the preparation
phase. Moreover, validate that family == NFPROTO_NETDEV and hook is
NF_NETDEV_INGRESS.
