I was trying to fill in the spec while exploring ethtool API for some
related work. I don't think I'll have the patience to fill in the rest,
so decided to share whatever I currently have.

Patches 1-2 add the be16 + spec.
Patches 3-4 implement an ethtool-like python tool to test the spec.

Patches 3-4 are there because it felt more fun do the tool instead
of writing the actual tests; feel free to drop it; sharing mostly
to show that the spec is not a complete nonsense.

The spec is not 100% complete, see patch 2 for what's missing.
I was hoping to finish the stats-get message, but I'm too dump
to implement bitmask marshaling (multi-attr).

Stanislav Fomichev (4):
  ynl: support be16 in schemas
  ynl: populate most of the ethtool spec
  ynl: replace print with NlError
  ynl: ethtool testing tool

Things that are not implemented:
- cable tests
- bitmaks in the requests don't work (needs multi-attr support in ynl.py)
- stats-get seems to return nonsense
- notifications are not tested
- features-nft has hard-coded value:13, not sure why it skews

  To: netdev; +Cc: davem, edumazet, kuba, pabeni, Stanislav Fomichev

Instead of dumping the error on the stdout, make the callee and
opportunity to decide what to do with it. This is mostly for the
ethtool testing.

This is what I've been using to see whether the spec makes sense.
A small subset of getters (mostly the unprivileged ones) is implemented.
Some setters (channels) also work.
Setters for messages with bitmasks are not implemented.

Initially I was trying to make this tool look 1:1 like real ethtool,
but eventually gave up :-)

Sample output:

$ ethtool enp0s31f6
Settings for enp0s31f6:
	Supported ports: [ TP ]
	Supported link modes:   10baseT/Half 10baseT/Full
	                        100baseT/Half 100baseT/Full
	                        1000baseT/Full
	Supported pause frame use: No
	Supports auto-negotiation: Yes
	Supported FEC modes: Not reported
	Advertised link modes:  10baseT/Half 10baseT/Full
	                        100baseT/Half 100baseT/Full
	                        1000baseT/Full
	Advertised pause frame use: No
	Advertised auto-negotiation: Yes
	Advertised FEC modes: Not reported
	Speed: Unknown!
	Duplex: Unknown! (255)
	Auto-negotiation: on
	Port: Twisted Pair
	PHYAD: 2
	Transceiver: internal
	MDI-X: Unknown (auto)
netlink error: Operation not permitted
        Current message level: 0x00000007 (7)
                               drv probe link
	Link detected: no

https://docs.kernel.org/next/userspace-api/netlink/specs.html#byte-order

byte-order: big-endian

Looks like it's slightly supported in ynl-gen-c but indeed the CLI 
lib doesn't have the parsing, yet.

ETHTOOL_MSG_FEATURES_SET_REPLY exists but there is no reply:

The following:
class A(Exception):
  def __repr__(self):
    return "{{{A}}}"
  def __str__(self):
    return "{{{B}}}"

raise A

Gets me this:
$ python3 tmp.py
Traceback (most recent call last):
  File "/usr/local/google/home/sdf/tmp/tmp.py", line 9, in <module>
    raise A
__main__.A: {{{B}}}


And for this:
class A(Exception):
  def __repr__(self):
    return "{{{A}}}"

raise A

I see:
$ python3 tmp.py
Traceback (most recent call last):
  File "/usr/local/google/home/sdf/tmp/tmp.py", line 7, in <module>
    raise A
__main__.A

It seems that __repr__ is mostly for repr()? And the rest is using
__str__? My pythonic powers are weak, can convert to __repr__ if you
prefer (or understand the difference).

Good point, will move to the binary. (but as I mentioned in the cover

{'grp': {'id': 1, 'ss-id': 18}}

But I guess that's because I'm not passing the group bitmask correctly?

Ah, good catch, I guess something like this would do? It doesn't have

Right. I guess the fact that I've never exercised "phc-vclocks-get" shows :-/

I used to know but I forgot. Let's leave it be unless someone chimes
