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).
Note, this is on top of net-next plus the following patch:
[PATCH net-next v4] tools: ynl: Add missing types to encode/decode
v3:
- reindent ethtool to 4 spaces
- byte_order=None to keep existing callers as is
- byte_order to SpecAttr
v2:
- be16 -> byte-order
- remove header in ethtool, not the lib
- NlError two spaces after
- s/_/-/ in ethtool spec
- add missing - for s32-array
- remove "value: 13" hard-code for features-ntf (empty reply instead)
- updated output of the sample run in the last patch (I was actually
using real ethtool, lol)
Stanislav Fomichev (4):
tools: ynl: support byte-order in cli
tools: ynl: populate most of the ethtool spec
tools: ynl: replace print with NlError

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 (not passing a bitmask properly?)
- notifications are not tested

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:
$ ./tools/net/ynl/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
Speed: Unknown!
Duplex: Unknown! (255)
Auto-negotiation: on
Port: Twisted Pair
PHYAD: 2
Transceiver: Internal
MDI-X: Unknown (auto)
Current message level: drv probe link
Link detected: no
