Subject: [PATCH net-next 0/7] IPSec offload improvements

From: Ilan Tayari <ilant@...lanox.com>

Hi Steffen,

This patchset introduces several improvements to IPSec offload.
We would like to see these merged in 4.14.

Patches 1-4 add RX checksum offload support.
This gives a big performance boost.
These patches have been submitted before but were not merged.
Note that patches 1-2 changed slightly with a call to skb_pull_rcsum.

Patch 5 adds automatic loading of XFRM offload modules, but only
if crypto-offload is explicitly requested by user.
This avoid issues in the field where user forgets to load the
module manually and so crypto-offload does not happen.

Patch 6 fixes the leftover xfrm_offload in RX SKBs.
This solves some issues with forwarding.

Patch 7 allows IPSec GSO on local sockets, with or without
crypto-offload.
This also gives a large performance boost.

Thanks,
Ilan.
