bc562be967 net/mlx5e: CT: Save ct entries tuples in hashtables
Save original tuple and natted tuple in two new hashtables.

This is a pre-step for restoring ct state after hw miss by performing a
5-tuple lookup on the hash tables.

e9716afdca net/mlx5: E-switch, When eswitch is unsupported, return -EOPNOTSUPP
When eswitch is unsupported, currently -EPERM error code is returned
instead of -EOPNOTSUPP.

Due to this VF device's devlink virtual port is not enumerated because
port_function_get() callback returned -EPERM instead of -EOPNOTSUPP.

Hence, return the error code -EOPNOTSUPP when eswitch is unsupported.

all rx frames and the decision whether a frame is a valid tls record
is done inside that function.  A function call can be expensive especially

jumping into the tls rx handler.

While at it, split between kTLS device offload rx handler and FPGA tls rx

Resync communication with HW for kTLS RX is done via the
async ICOSQs.
kTLS RX resync requests might come in bursts. To improve the
success chances for such bursts, use a larger ICOSQ.

0419d8c9d8 net/mlx5e: kTLS, Add kTLS RX resync support
Implement the RX resync procedure, using the TLS async resync API.

The HW offload of TLS decryption in RX side might get out-of-sync
due to out-of-order reception of packets.
This requires SW intervention to update the HW context and get it
back in-sync.

1182f36593 net/mlx5e: kTLS, Add kTLS RX HW offload support
Implement driver support for the kTLS RX HW offload feature.
Resync support is added in a downstream patch.

New offload contexts post their static/progress params WQEs
over the per-channel async ICOSQ, protected under a spin-lock.
The Channel/RQ is selected according to the socket's rxq index.

Feature is OFF by default. Can be turned on by:
$ ethtool -K <if> tls-hw-rx-offload on

A new TLS-RX workqueue is used to allow asynchronous addition of
steering rules, out of the NAPI context.
It will be also used in a downstream patch in the resync procedure.

7d0d0d86ec net/mlx5e: kTLS, Improve TLS feature modularity
Better separate the code into c/h files, so that kTLS internals
are exposed to the corresponding non-accel flow as follows:
- Necessary datapath functions are exposed via ktls_txrx.h.
- Necessary caps and configuration functions are exposed via ktls.h,
  which became very small.

In addition, kTLS internal code sharing is done via ktls_utils.h,
which is not exposed to any non-accel file.

Add explicit WQE structures for the TLS static and progress
params, breaking the union of the static with UMR, and the progress
with PSV.

Generalize the API as a preparation for TLS RX offload support.

Move kTLS TX-specific code to the proper file.
Remove the inline tag for function in C files, let the compiler decide.
Use kzalloc/kfree for the priv_tx context.

8d94b590f1 net/mlx5e: Turn XSK ICOSQ into a general asynchronous one
There is an upcoming demand (in downstream patches) for
an ICOSQ to be populated out of the NAPI context, asynchronously.

There is already an existing one serving XSK-related use case.
In this patch, promote this ICOSQ to serve as general async ICOSQ,
to be used for XSK and non-XSK flows.

As part of this, the reg_umr bit of the SQ context is now set
(if capable), as the general async ICOSQ should support possible
posts of UMR WQEs.
