We are disappointed because at PGCon talk Huawei announced publishing of
their CSN patch and further work in this direction together with community.
However, it's even not published yet despite all the promises. Nobody from
Huawei answers CSN thread in the hackers.
So, I think we got nothing from Huawei except teasing and should rely only
on ourselves. That is disappointing.
