Subject: ifb: Depend on netfilter alternatively to tc
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e094a99911da13909607278ac60f7aa874f715d3;p=linux.git

ifb: Depend on netfilter alternatively to tc

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.
