Subject: Re: [PATCH 1/2] xfrm: add SA information to the offloaded packet

Hi Leon,
I checked the current tree and there are no drivers who support packet
offload. Even for the mlx5 driver, it only supports crypto offload
mode. If I miss anything, please let me know.
Since the driver only requires the Security Association (SA) to
perform the necessary transformations,  policy information is not
needed. Storing policy information, matching the policy and checking
the if_id within the driver wouldn't provide much benefit. It would
increase CPU and memory usage without a clear advantage.
For all other suggestions, I totally agree with you.

Thanks,
Feng
