The user tool modinfo is used to get information on kernel modules, including a
description where it is available.
This patch adds a brief MODULE_DESCRIPTION to netfilter kernel modules
(descriptions taken from Kconfig file or code comments)

module is disabled
If IPv6 is disabled on boot (ipv6.disable=1), but nft_fib_inet ends up
dealing with a IPv6 packet, it causes a kernel panic in
fib6_node_lookup_1(), crashing in bad_page_fault.
The panic is caused by trying to deference a very low address (0x38
in ppc64le), due to ipv6.fib6_main_tbl = NULL.
BUG: Kernel NULL pointer dereference at 0x00000038
The kernel panic was reproduced in a host that disabled IPv6 on boot and
have to process guest packets (coming from a bridge) using it's ip6tables.
Terminate rule evaluation when packet protocol is IPv6 but the ipv6 module
is not loaded.

Add fib expression support for netdev family. Like inet family, netdev
delegates the actual decision to the corresponding backend, either ipv4
or ipv6.
This allows to perform very early reverse path filtering, among other
things.
You can find more information about fib expression in the f6d0cbcf09c5
("<netfilter: nf_tables: add fib expression>") commit message.
