Subject: [PATCH 5.10 102/575] ifb: Depend on netfilter alternatively to tc

From: Lukas Wunner <lukas@...ner.de>

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")
