Hi all,

Thanks for reviewing

Are we talking about testsuites tests that use legacy networking? If
so, then I have already shifted the networking01.exe and will shift
other tests using the same approach.

This is a good point! I'll probably just keep it as a README in the
net-legacy repo.

Yes, these are mostly bsp.h files. I'll file a ticket and post to
users and devel about it. There are also quite a few with

Thank you. :)

Sure, I'll rename it and force push.

pep8 does work for me when used manually but with waf module I'm
getting the following error:

  File "/home/vijay/.local/lib/python3.8/site-packages/", line
253, in maximum_line_length
    if length > options.max_line_length:
AttributeError: 'Values' object has no attribute 'max_line_length'
This is strange because it looks like an error in the pep8 module itself.

I have tried different versions of pep8 and it looks like each version
has a different error. I think this needs some work from the waf side
to get it working with the new pycodestyle instead of the pep8 module.

I gave it a few shots but it didn't quite work out well for me.  I do
get the generator from it but for some reason, it's not building. We
would also need the list of headers for the install, for which I think
os.walk might be needed.

Is this a blocker to merging? If so, then I can put more time into it
and try to get it working. If you want it as an optimization, maybe we
could merge it and file a ticket? I can take more time and fix it

This is a good point, The README needs some update for sure. I'll
follow the README.waf from other repos and follow the same pattern.

I'll do it along with the README and send it for review.

I can already see a small issue from my side. The networking01.yml is
there. That will go away, along with some other testsuites yml that
I'll shift now. Do we need ticket for the rest?
