If we enforce by policy we need to use the constant 7, not the macro
IEEE_8021QAZ_MAX_TCS-1.
I'll keep it.

The spec should support using "foreign constants"
Off the top of my head - you can define the ieee-8021qaz-max-tcs contant
as if you were defining a devlink constant, then add a header:
attribute. This will tell C codegen to include that header instead of
generating the definition.
   

Hi Jakub,

I tried implementing this as you suggested, but it seems that the only
supported definition types are ['const', 'enum', 'flags', 'struct'],
while the max value in checks only accepts patterns matching
^[su](8|16|32|64)-(min|max)$.

  From what I see, it doesn’t currently support using a const value for
the max or min checks. Let me know if I’m missing something or if
there’s an alternative way to achieve this.

Ah, I thought we already implemented this, sorry.
Can you try the two patches from the top of this branch?

Yes, it worked after applying the pattern changes to the
genetlink-legacy.yaml , as devlink uses it.

Thank you!

Carolina
