Set up for software based CMAC operation.

This function initializes a CMAC operation with the provided key attributes and key buffer. It prepares the operation structure for subsequent CMAC processing. This operation runs cmac in software using hardware AES-ECB primitives

Parameters

[in,out]	op	Pointer to the CMAC operation structure to be initialized.
[in]	attributes	Pointer to the key attributes structure.
[in]	key_buffer	Pointer to the buffer containing the key material.
[in]	key_buffer_size	Size of the key buffer in bytes.

Returns

PSA_SUCCESS on success or a valid PSA status code.
