[PATCH nft v2 0/5] src: mnl: rework list hooks infra

[Florian Westphal <fw@strlen.de>]

Turns out that not only was 'nft list hooks' mostly undocumented,
there was also confusion on what it should do.

First, clean this code up and make it strictly a tool to dump
the NFPROTO_X registered functions.

Then, remove the 'hook' function argument, this was still passed
from back in the day when one could ask to only dump e.g.
ipv4 prerouting.  This ability is of little value, so don't restore
this but instead just remove the leftover code.

Next, allow dumping of netdev:egress hooks.
Lastly, document this in more detail and make it clear that this
dumps the netfilter hooks registered for the protocol families,
and nothing else.

Once this gets applied I intend to make
'nft list hooks netdev'

dump device hooks for all interfaces, if any, instead of a
'no device provided' warning.
