mlx4 XDP performance improvements
This patchset contains data-path improvements, mainly for XDP_DROP
and XDP_TX cases.
Main patches:
* Patch 2 by Saeed allows enabling optimized A0 RX steering (in HW) when
setting a single RX ring.
With this configuration, HW packet-rate dramatically improves,
reaching 28.1 Mpps in XDP_DROP case for both IPv4 (37% gain)
and IPv6 (53% gain).
* Patch 6 enhances the XDP xmit function. Among other changes, now we
ring one doorbell per NAPI. Patch gives 17% gain in XDP_TX case.
* Patch 7 obsoletes the NAPI of XDP_TX completion queue and integrates its
poll into the respective RX NAPI. Patch gives 15% gain in XDP_TX case.

Some code re-ordering, functionally equivalent.
- The !tx_info->inl check is evaluated anyway in both flows
(common case/end case). Run it first, this might finish
the flows earlier.
- dma_unmap calls are identical in both flows, get it out
of the if block into the common area.

Instead of having their own NAPIs, XDP TX completion queues get
polled within the corresponding RX NAPI.
This prevents any possible race on TX ring prod/cons indices,
between the context that issues the transmits (RX NAPI) and the
context that handles the completions (was previously done in
a separate NAPI).
This also improves performance, as it decreases the number
of NAPIs running on a CPU, saving the overhead of syncing
and switching between the contexts.

This series of small patches is meant to resolve a number of

recovering from a logical partition migration (LPM).
The first patch ensures that RX buffer pools are properly
activated following an adapter reset by setting the proper
flag in the pool data structure.
The second patch uses netif_tx_disable to stop TX queues when
closing the device during a reset.
Third, fixup a typo that resulted in partial sanitization of
TX/RX descriptor queues following a device reset.
Fourth, remove an ambiguous conditional check that was resulting
in a kernel panic as null RX/TX completion descriptors were being
processed during napi polling while the device is closing.
Finally, fix a condition where the napi polling routine exits
before it has completed its work budget without notifying the
upper network layers. This omission could result in the
napi_disable function sleeping indefinitely under certain conditions.

net: kernel TLS
This series adds support for kernel TLS encryption over TCP sockets.
A standard TCP socket is converted to a TLS socket using a setsockopt.
Only symmetric crypto is done in the kernel, as well as TLS record
framing. The handshake remains in userspace, and the negotiated
cipher keys/iv are provided to the TCP socket.
We implemented support for this API in OpenSSL 1.1.0, the code is
available at https://github.com/Mellanox/tls-openssl/tree/master
It should work with any TLS library with similar modifications,
a test tool using gnutls is here: https://github.com/Mellanox/tls-af_ktls_tool
RFC patch to openssl:

Changes from V2:
* EXPORT_SYMBOL_GPL in patch 1
* Ensure cleanup code always called before sk_stream_kill_queues to

* Add link to OpenSSL patch & gnutls example in documentation patch.
* sk_write_pending check was rolled in to wait_for_memory path,
avoids special case and fixes lock inbalance issue.
* Unify flag handling for sendmsg/sendfile
Changes from RFC V2:
* Generic ULP (upper layer protocol) framework instead of TLS specific
setsockopts
* Dropped Mellanox hardware patches, will come as separate series.
Framework will work for both.

* Zerocopy sendmsg support added - sendpage/sendfile is no longer
necessary for zerocopy optimization
RFC V1:

Add the infrustructure for attaching Upper Layer Protocols (ULPs) over TCP
sockets. Based on a similar infrastructure in tcp_cong. The idea is that any
ULP can add its own logic by changing the TCP proto_ops structure to its own
methods.
Example usage:
setsockopt(sock, SOL_TCP, TCP_ULP, "tls", sizeof("tls"));
modules will call:
tcp_register_ulp(&tcp_tls_ulp_ops);
to register/unregister their ulp, with an init function and name.
A list of registered ulps will be returned by tcp_get_available_ulp, which is
hooked up to /proc. Example:
$ cat /proc/sys/net/ipv4/tcp_available_ulp
tls
There is currently no functionality to remove or chain ULPs, but
it should be possible to add these in the future if needed.
