Subject: [RFC PATCH rdma-next 00/18] Flow actions to mutate packets

From: Leon Romanovsky <leonro@...lanox.com>

Hi,

This series from Mark is marked as RFC due to the fact that it is under
final stages of internal review - commit messages, patch reordering and
internal agreement if "{net, RDMA}/mlx5: Rename encap to reformat packet"
is needed.

Because the main logic and functionality are not expected to change, we
would like to post it the mailing list and gather broader feedback than
we can achieve internally.

We will resubmit it without RFC tag once review will complete.

Thanks

>From Mark:
This series exposes the ability to create flow actions which can
mutate packet headers. We do that by exposing two new verbs:
 * modify header - can change existing packet headers. packet
 * reformat - can encapsulate or decapsulate a packet.
              Once created a flow action must be attached to a steering
              rule for it to take effect.

Thanks
