Re: [dpdk-dev] [PATCH 0/7] net/mlx5: support for flow action on VLAN header

[Hideyuki Yamashita <yamashita.hideyuki@ntt-tx.co.jp>]

Dear Slava,

Your guess is corrrect.
When I put flow into Connect-X5, it was successful.

General question.
Are there any way to input flow to ConnectX-4?
In another word, are there any way to activate Verb?
And which type of flow is supported in Verb?
