Do you want to intentionally move to the normal naming or would you
prefer to keep the old names?

We have attr-cnt-name / attr-max-name for migrating existing families.
We can add similar properties for cmd if you prefer, I think that they
were not needed before.

I'm not sure if you're offering to add the feature or are asking us (well, 
Davide) to implement it :)

It would be nice to not have to carry these backward compatibility 
definitions forever, expecially since they're fairly obscure "__*" 
names. Low stakes for MPTCP alone, but it might be good to have as other 
netlink interfaces are migrated.

Davide & Paolo, what do you think?

Either way is fine, Davide seems to have tackled the extensions in patches 
1 and 2, so he may want to do it himself. Otherwise I'm more than happy
to type and send the patch :)

Let's make sure we update documentation, tho, in this case:
Documentation/userspace-api/netlink/c-code-gen.rst

To be clear - assuming you do actually want to keep using the old names.

hello,

thanks for looking at this.

given that nobody should use them, I'd prefer to move to the normal
naming and drop the old definitions (_MPTCP_PM_CMD_AFTER_LAST and
__MPTCP_ATTR_AFTER_LAST). I was unsure if I could do the drop thing
actually, because applications using them would break the build then _
hence these two "backward compatibility" lines.

For the operation list, I see it's about exposing

cmd-cnt-name

to [ge]netlink*.yaml, and then do:

  9 max-by-define: true
 10 kernel-policy: per-op
 11 cmd-cnt-name: --mptcp-pm-cmd-after-last    <-- this
 12
 13 definitions:

the generated MPTCP #define(s) are the same as the ones we have in
net-next now: no need to specify __MPTCP_PM_CMD_MAX anymore.

For the attributes, I thought I could use  'attr-cnt-name' like:

169     name: attr
170     name-prefix: mptcp-pm-attr-
171     attr-cnt-name: --mptcp-attr-after-last <-- this
172     attributes:

as described in the [ge]netlink schema, but the tool seems to just ignore it.

It's up to you. Only mention on GitHub I see is this:
https://github.com/ngi-mptcp/mptcpanalyzer/blob/d6f5a4a61235f40dd17b1ef394a91ec50eda53f7/mptcp-pm/src/Net/Mptcp/V0/Constants.chs#L34
No idea what it is and whether the define disappearing will break it.

If you're confident that no code will break we can rename.
The downside (other than an angry user) is that if someone reports
breakage late we may need to keep both names, to avoid breaking any
code created in between..

Ah, I was looking at the documentation which is clearly out of date
already..

Mm. Looks like we only use this one at the family level.
