Currently nft dumps core when it encounters a prefix expression as
part of a statement, e.g.
iifname ens3 snat to 10.0.0.0/28
yields:
BUG: unknown expression type prefix
nft: netlink_linearize.c:688: netlink_gen_expr: Assertion `0' failed.
This assertion is correct -- we can't linearize a prefix because
kernel doesn't know what that is.
For LHS prefixes, they get converted to a binary 'and' such as
'10.0.0.0 & 255.255.255.240'. For RHS, we can do something similar
and convert them into a range.
snat to 10.0.0.0/28 will be converted into:
iifname "ens3" snat to 10.0.0.0-10.0.0.15

This special operator is required for cases where missing operator does
not lead to same results as equal operator, i.e. with bitmasks on RHS.

For raw payloads, property "name" is not needed, it's clearly identified
by base/offset/len properties.
In non-raw payload expressions, rename property "name" to "protocol" as
suggested during NFWS.

This extends nft-test.py by optional JSON testing capabilities,
activated via '-j'/'--enable-json' parameter).
JSON testing happens for all rules which are supposed to work: After a
rule has been added and the existing tests (payload, ruleset listing
output) have been performed, basically the same test is done again using
a recorded JSON equivalent and (if necessary) a recorded listing output.
The code tries to ease new test case creation overhead by
auto-generating JSON equivalent input via listing the (non-JSON) rule in
JSON format. Also, differing netlink debug and listing output are stored
in *.got files to assist in analyzing/fixing failing test cases.
