[ovs-dev] [PATCH RFC] ofproto: RFC extended statistics patch

Hello, 

"Wouldn't it make more sense to use the OF1.5 extensible port statistics
feature?"
[MW] To be honest I double checked the OF1.5 documentation, and did you mean "Extensible Flow Statistics - OXS"? 
At least I can't find anything about Extensible port statistics. I've also checked the code, however I can't find 
any generic way to implement it without protocol extension. If you meant, that this could be achieved by creating flow
statistics extension, this is not exactly what my patch implements, which is port-based statistics. 

Could you point me to any exact code/documentation if none of above answers are valid? 

Br, 
Michal.

Wouldn't it make more sense to use the OF1.5 extensible port statistics
feature?
