Subject: [PATCH xfrm-next 0/9] Extend packet offload to fully support libreswan

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

Hi Steffen,

The following patches are an outcome of Raed's work to add packet
offload support to libreswan [1].

The series includes:
 * Priority support to IPsec policies
 * Statistics per-SA (visible through "ip -s xfrm state ..." command)
 * Support to IKE policy holes
 * Fine tuning to acquire logic.

--------------------------
Future submission roadmap, which can be seen here [2]:
 * Support packet offload in IPsec tunnel mode
 * Rework lifetime counters support to avoid HW bugs/limitations
 * Some general cleanup.

So how do you want me to route the patches, as they have a dependency between them?
xfrm-next/net-next/mlx5-next?

Thanks

Paul Blakey (3):
  net/mlx5: fs_chains: Refactor to detach chains from tc usage
  net/mlx5: fs_core: Allow ignore_flow_level on TX dest
  net/mlx5e: Use chains for IPsec policy priority offload

Raed Salem (6):
  xfrm: add new device offload acquire flag
  xfrm: copy_to_user_state fetch offloaded SA packets/bytes statistics
  net/mlx5e: Allow policies with reqid 0, to support IKE policy holes
  net/mlx5e: Support IPsec acquire default SA
  net/mlx5e: Use one rule to count all IPsec Tx offloaded traffic
  net/mlx5e: Update IPsec per SA packets/bytes count
