I recently submitted some NC-SI changes ([1], [2]) to libslirp, and I'd like
to include them as netdev options in QEMU now.
I'm guessing that before we can do that though, there probably needs
to be a new libslirp release, right? Right now we're on 4.7.0, with
SlirpConfig version 4. I guess I'd like to create (or wait, either
is fine) 4.8.0, and update QEMU to use SlirpConfig version 5 if
that version is available.
By the way: do I need to add #if SLIRP_CHECK_VERSION(4,7,0) around any code
I'm adding? I'm hoping that's not the case, but I see that was necessary
with the recent timer changes.
Let me know what I should do, I am fully expecting that I'll need to either
wait for the next slirp release, submit a v2, etc. Just wanted to get the
ball rolling.
Thanks,
Peter

There hasn't been a new libslirp release yet, but I don't see any reason
in particular why we couldn't update to this commit to support the new
NC-SI functionality added in !122 and !125, as long as it doesn't break
backwards compatibility with anything.

I think we probably need a new Slirp release
(4.8.0) and a switch statement here instead, right?
So that we can preserve the behavior for 4.7.0?

This lets you set the manufacturer's ID for a slirp netdev, which can be
queried from the guest through the Get Version ID NC-SI command. For
example, by setting the manufacturer's ID to 0x8119:
wget https://github.com/facebook/openbmc/releases/download/openbmc-e2294ff5d31d/fby35.mtd
qemu-system-arm -machine fby35-bmc \
-drive file=fby35.mtd,format=raw,if=mtd -nographic \
-netdev user,id=nic,mfr-id=0x8119,hostfwd=::2222-:22 \
-net nic,model=ftgmac100,netdev=nic
...

You will need a #if to only include it with slirp 4.8.0 indeed.
Otherwise the mfr_id field won't exist.
In the #else part, it would probably useful to give the user at least a
warning that tells her to upgrade slirp to 4.8.0 to get the mfr_id
functionality working.

Is 'mfr-id' an established technical term, or an abbreviation you came
up with? If the latter, please use @manufacturer-id instead.
Documentation is rather terse. It basically provides a bunch of
keywords you can throw at the search engine of your choice. Can we cut
out that middle man and point straight to a suitable resource?

Is 'mfr-id' an established technical term, or an abbreviation you came
up with? If the latter, please use @manufacturer-id instead.
I don’t think so, I used that particular variable name throughout these patches
because that’s what the Linux kernel driver was using, but you’re right, we should
not use an abbreviation, in v2 I’ll change it to @manufacturer-id.
Documentation is rather terse. It basically provides a bunch of
keywords you can throw at the search engine of your choice. Can we cut
out that middle man and point straight to a suitable resource?
Erg, yeah, sorry about that, you’re right, it would probably be more useful
to point to the NC-SI specification directly:
https://www.dmtf.org/sites/default/files/standards/documents/DSP0222_1.0.0.pdf
Note: there have been some newer revisions to the specification lately, and the
full list of spec versions is here:
https://www.dmtf.org/dsp/DSP0222
Get Version ID and the OEM Vendor extension are both specified in 1.0.0, so I
think it should be ok to link to 1.0.0.
I’m not totally sure if I should directly link to the actual URL, but I’ll
definitely say: “This is defined in DMTF NC-SI 1.0.0” or something like that.
Unless URL’s in the code would be preferred. Theoretically, the DMTF
spec URL should be pretty long-lasting.
Thanks,
Peter

Oh, right. I’ll test this code with 4.7.0 and 4.8.0 and make
sure the behavior is correct (and perhaps even with earlier
versions like 1.0).

Feel free to add URL, too.
