c6b552e4c0 vdpa/mlx5: fix overflow in queue attribute
The mlx5_vdpa_event_qp_create function makes shifting to the numeric
constant 1, then multiplies it by another constant and finally assigns
it into a uint64_t variable.

The numeric constant type is an int with a 32-bit sign. if after
shifting , its MSB (bit of sign) will change, the uint64 variable will
get into it a different value than what the function intended it to get.

Set the numeric constant 1 to be uint64_t in the first place.

c87bc83a33 compress/mlx5: fix overflow in queue size
The mlx5_compress_qp_setup function makes shifting to the numeric
constant 1, then sends it as a parameter to rte_calloc function.

The rte_calloc function expects to get size_t (might be 64 bit) and
instead gets a 32-bit variable, because the numeric constant size is a
32-bit.
In case the shift is greater than 32 bit and it 64-system, the variable
will lose its value even though the function can get 64-bit argument.

Change the size of the numeric constant 1 to size_t.

423719a367 regex/mlx5: fix size of setup constants
The constant representing the size of the metadata is defined as an
unsigned int variable with 32-bit.
Similarly the constant representing the maximal output is also defined
as an unsigned int variable with 32-bit.

There is potentially overflowing expression when those constants are
evaluated using 32-bit arithmetic, and then used in a context that
expects an expression of type size_t that might be 64-bit.

Change the size of the above constants to size_t.

4d648fad90 net/mlx5: check consistency of meter policy and profile
In the previous implementation, only green color policy was
supported in mlx5 PMD. Since yellow color policy is supported now,
the consistency of meter policy and profile should be checked.
  1. If the profile supports yellow but the policy doesn't, an error
     should be returned when creating the meter. Or else, there is
     no explicit steering action for the packets marked with yellow.
  2. If the policy supports yellow but the profile doesn't, it will
     be considered as a valid case. Even if no packet will be
     handled with the yellow steering action, it is just like that
     only the green policy presents.

Usually the green color is supported by default, but when it is
disabled intentionally with setting the CBS to a small value like
zero in the profile, the similar checking on green policy and
profile should also be done.

4b7bf3ffb4 net/mlx5: support yellow in meter policy validation
In the previous implementation, the policy for yellow color was not
supported. The action validation for yellow was skipped.

Since the yellow color policy needs to be supported, the validation
should also be done for the yellow color. In the meanwhile, due to
the fact that color policies of one meter should be used for the
same flow(s), the domains supported of both colors should be the
same. If both of the colors have RSS as the termination actions,
except the queues, all other parameters of RSS should be the same.

b38a12272b net/mlx5: split meter color policy handling
If the fate action is either RSS or Queue of a meter policy, the
action will only be created in the flow splitting stage. With queue
as the fate action, only one sub-policy is needed. And RSS will
have more than one sub-policies if there is an expansion.

Since the RSS parameters are the same for both green and yellow
colors except the queues, the expansion result will be unique.
Even if only one color has the RSS action, the checking and possible
expansion will be done then. For each sub-policy, the action rules
need to be created separately on its own policy table.

fa31a5ed01 net/mlx5: support yellow meter policy rules
When creating a meter policy, both / either of the action rules for
green and yellow colors may be provided. After validation, usually
the actions are created before the meter is using by a flow rule.

If there is action specified for the yellow color, the action rules
should be created together with green color in the same time. The
action of green / yellow color can be empty, then the default
behavior is the jump action of the rule, just the same as that of
the default policy.

If the fate action of either one color is queue / RSS, all the
actions rules will be created on the flow splitting stage instead of
the policy adding stage.

9b5463df5d net/mlx5: enable meter bucket overflow for yellow color
To support the meter policy for yellow action, the prerequisite is
that the hardware needs to support the EBS, as defined in the
RFC2697.
  https://datatracker.ietf.org/doc/html/rfc2697
Then some of the packets can be marked as yellow if the tokens of C
bucket is not enough but enough in E bucket. The color could be used
for the further steering of the packets.

In the current implementation EBS and overflow were ignored when
creating a meter profile. With this commit, if EBS is set by the
application, the generation of yellow color will be enabled in the
hardware for flow rules steering of packets.

ad435d3204 common/mlx5: add bus-agnostic layer
To support auxiliary bus, introduces common device driver and callbacks,
supposed to replace mlx5 common PCI bus driver.

Mlx5 class drivers, i.e. eth, vDPA, regex and compress normally consumes
single Verbs device context to probe a device. The Verbs device comes
from PCI address if the device is PCI bus device, from Auxiliary sysfs
if the device is auxiliary bus device. Currently only PCI bus is
supported.

Common device driver is a middle layer between mlx5 class drivers and
bus, resolve and abstract bus info to Verbs device for class drivers.
Both PCI bus driver and Auxiliary bus driver can utilize the common
driver layer to cast bus operations to mlx5 class drivers.

Legacy mlx5 common PCI bus driver still being used by mlx5 eth, vDPA,
regex and compress PMD, will be removed once all PMD drivers
migrate to new common driver.

a1978aa23b crypto/mlx5: add maximum segments configuration
The mlx5 HW crypto operations are done by attaching crypto property
to a memory region. Once done, every access to the memory via the
crypto-enabled memory region will result with in-line encryption or
decryption of the data.

As a result, the design choice is to provide two types of WQEs. One
is UMR WQE which sets the crypto property and the other is rdma write
WQE which sends DMA command to copy data from local MR to remote MR.

The size of the WQEs will be defined by a new devarg called
max_segs_num.

This devarg also defines the maximum segments in mbuf chain that will be

e8db4413cb crypto/mlx5: add keytag configuration
A keytag is a piece of data encrypted together with a DEK.

When a DEK is referenced by an MKEY.bsf through its index, the keytag is
also supplied in the BSF as plaintext. The HW will decrypt the DEK (and
the attached keytag) and will fail the operation if the keytags don't
match.

This commit adds the configuration of the keytag with devargs.

debb27ea34 crypto/mlx5: create login object using DevX
To work with crypto engines that are marked with wrapped_import_method,
a login session is required.
A crypto login object needs to be created using DevX.

The crypto login object contains:
	- The credential pointer.
	- The import_KEK pointer to be used for all secured information
	  communicated in crypto commands (key fields), including the
	  provided credential in this command.
	- The credential secret, wrapped by the import_KEK indicated in
	  this command. Size includes 8 bytes IV for wrapping.

Added devargs for the required login values:
	- wcs_file - path to the file containing the credential.
	- import_kek_id - the import KEK pointer.
	- credential_id - the credential pointer.

Create the login DevX object in pci_probe function and destroy it in
pci_remove.
Destroying the crypto login object means logout.

247ad1305a crypto/mlx5: add memory region management
Mellanox user space drivers don't deal with physical addresses as part
of a memory protection mechanism.
The device translates the given virtual address to a physical address
using the given memory key as an address space identifier.
That's why any mbuf virtual address is moved directly to the HW
descriptor(WQE).

The mapping between the virtual address to the physical address is saved
in MR configured by the kernel to the HW.

Each MR has a key that should also be moved to the WQE by the SW.

When the SW sees an unmapped address, it extends the address range and
creates a MR using a system call.

Add memory region cache management:
	- 2 level cache per queue-pair - no locks.
	- 1 shared cache between all the queues using a lock.

Using this way, the MR key search per data-path address is optimized.

1004be3c03 crypto/mlx5: support session operations
Sessions are used in symmetric transformations in order to prepare
objects and data for packet processing stage.

A mlx5 session includes iv_offset, pointer to mlx5_crypto_dek struct,
bsf_size, bsf_p_type, block size index, encryption_order and encryption
standard.

Implement the next session operations:
        mlx5_crypto_sym_session_get_size- returns the size of the mlx5
	session struct.
	mlx5_crypto_sym_session_configure- prepares the DEK hash-list
	and saves all the session data.
	mlx5_crypto_sym_session_clear - destroys the DEK hash-list.

6152534e21 crypto/mlx5: support queue pairs operations
The HW queue pairs are a pair of send queue and receive queue of
independent work queues packed together in one object for the purpose
of transferring data between nodes of a network.

Completion Queue is a FIFO queue of completed work requests.

In crypto driver we use one QP in loopback in order to encrypt and
decrypt data locally without sending it to the wire.
In the configured QP we only use the SQ to perform the encryption and
decryption operations.

Added implementation for the QP setup function which creates the CQ,
creates the QP and changes its state to RTS (ready to send).

Added implementation for the release QP function to release all the QP
resources.

Added the ops structure that contains any operation which is supported
by the cryptodev.
