Merge branch 'mlx5-TLS-TX-HW-offload-support'

Tariq Toukan says:

====================
mlx5 TLS TX HW offload support

This series from Eran and me, adds TLS TX HW offload support to
the mlx5 driver.

This offloads the kTLS encryption process from kernel to the
Mellanox NIC, saving CPU cycles and improving utilization.

Upon a new TLS connection 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.
Series was tested on SimX simulator.

Series generated against net-next commit [1], with Saeed's request pulled [2]:

[1] c4cde5804d51 Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
[2] git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git tags/mlx5-updates-2019-07-04-v2

Changes from last pull request:
Fixed comments from Jakub:
Patch 4:
- Replace zero  memset with a call to memzero_explicit().
Patch 11:
- Fix stats counters names.
- Drop TLS SKB with non-matching netdev.
