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") Signed-off-by: Lukas Wunner <lukas@wunner.de> Cc: <stable@vger.kernel.org> # v4.5+: bcfabee1afd9: netfilter: nft_fwd_netdev: allow to redirect to ifb via ingress Cc: <stable@vger.kernel.org> # v4.5+ Signed-off-by: David S.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
