Subject: [PATCH] ifb: Depend on netfilter alternatively to tc
Git-commit: 046178e726c2977d686ba5e07105d5a6685c830e
Patch-mainline: v5.16-rc1
References: stable-5.14.19
commit 046178e726c2977d686ba5e07105d5a6685c830e upstream.
IFB originally depended on NET_CLS_ACT for traffic redirection.
But since v4.5, that may be achieved with NFT_FWD_NETDEV as well.
Fixes: 39e6dea28adc ("netfilter: nf_tables: add forward expression to the netdev family")
