As I know, Jingguo was trying to verify more cases (such as jumbo frame forward between VM to VM ) with this v3 patch,
I think he finish all test cases today, so send this mail.

And I think he also validate these 2 patches in his recent validation work:

jingguo, am I correct?

Thanks and regards,

Changchun
