Subject: [pull request][net-next 00/14] Mellanox, mlx5 updates 2019-07-04

Hi Dave,

This series adds two features to mlx5 driver.
1) From Shay, add the support for devlink fw query
2) From Tariq and Eran, KTLS tx support.

For more information please see tag log below.

Please pull and let me know if there is any problem.

Please note that the series starts with a merge of mlx5-next branch,
to resolve and avoid dependency with rdma tree.
This what was actually missing from my previous submission of the 2
devlink patches.

Thanks,
Saeed.

  net/mlx5e: Add kTLS TX HW offload support (2019-07-04 14:04:31 -0400)

----------------------------------------------------------------
mlx5-update-2019-07-04

This series provides the following mlx5 updates

1) Add the support for devlink fw versions query.

2) Driver support for kernel-TLS transmit HW offload
This offloads the kTLS encryption process from kernel to the
Mellanox NIC, saving CPU cycles and improving utilization.
Upon a new TLS conneciton request, driver is responsible to create
a dedicated HW context and configure it according to the crypto info,
so HW can do the encryption itself.

When the HW context gets out-of-sync (i.e. due to packets retransmission),
driver is responsible for the re-sync process.
This is done by posting special resync descriptors to the HW.
Feature is supported on Mellanox Connect-X 6DX, and newer.
