Thanks a lot for the review, Flavio.
Excuse my lack of attention to the details. I miss something like
checkpatch on Linux, that would take care of some of the coding style
problems one may find in a patch. Is there any recommendations on that
for OVS?
I have a v5 prepared, but will wait for any other comments before I send
it.
