The documentation describes the syntax of limit statements thus:
limit rate [over] packet_number / TIME_UNIT [burst packet_number packets]
limit rate [over] byte_number BYTE_UNIT / TIME_UNIT [burst byte_number BYTE_UNIT]
TIME_UNIT := second | minute | hour | day
BYTE_UNIT := bytes | kbytes | mbytes
From this one might infer that a limit may be specified by any of the
following:
limit rate 1048576/second
limit rate 1048576 mbytes/second
limit rate 1048576 / second
limit rate 1048576 mbytes / second
However, the last does not currently parse:
$ sudo /usr/sbin/nft add filter input limit rate 1048576 mbytes / second
Error: wrong rate format
add filter input limit rate 1048576 mbytes / second
^^^^^^^^^^^^^^^^^^^^^^^^^
Extend the `limit_rate_bytes` parser rule to support it, and add some
new Python test-cases.

Add userspace support for the netdev egress hook which is queued up for
v5.16-rc1, complete with documentation and tests. Usage is identical to
the ingress hook.

Burst can be either bytes or packets, depending on the rate limit unit.
# nft add rule x y iif eth0 limit rate 512 kbytes/second burst 5 packets
Error: syntax error, unexpected packets, expecting string or bytes
add rule x y iif eth0 limit rate 512 kbytes/second burst 5 packets
^^^^^^^

So far it was only possible to match packet under a rate limit, this
patch allows you to explicitly indicate if you want to match packets
that goes over or until the rate limit, eg.
... limit rate over 3/second counter log prefix "OVERLIMIT: " drop
... limit rate over 3 mbytes/second counter log prefix "OVERLIMIT: " drop
... ct state invalid limit rate until 1/second counter log prefix "INVALID: "
When listing rate limit until, this shows:
... ct state invalid limit rate 1/second counter log prefix "INVALID: "
thus, the existing syntax is still valid (i.e. default to rate limit until).

This patch enables tests for the new netdev family and its ingress
chain.

Rearrange the directory to obtain a better organization of files and
tests-suites.
We end with a tree like this:
tests
|
.--- py
.--- shell
.--- files
This was suggested by Pablo.
