Subject: ifb: Depend on netfilter alternatively to tc
From: Lukas Wunner <lukas@xxxxxxxxx>
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")
