Can the "fib" nftables statement options be added to VyOS firewall and nat configuration options per:
https://wiki.nftables.org/wiki-nftables/index.php/Matching_routing_information ?

fib:
The fib statement can be used to obtain the output interface from the route table based on either source or destination address of a packet. This can be used to e.g. add reverse path filtering, or eg. drop if not coming from the same interface packet arrived on.

General syntax is: fib key data operator expression, where:

    key: saddr, daddr, mark, iif, oif (use '.' for concatenations to represent tuples)
    data: oif, oifname, (address) type
    operator: eq, neq, vmap, map

It would be useful to have these options available in general firewall and nat configuration nodes in VyOS, for example:

set nat destination rule 100 fib <key> <data> <operator> expression

set firewall name OUTSIDE-IN rule 100 fib <key> <data> <operator> expression

Please refer to provided nftables wiki link for further example usage/syntax.

Thank you!
