## Detailed Description

A struct containing all of the function pointers needed to perform secure element MAC operations.

PSA Crypto API implementations should populate the table as appropriate upon startup.

If one of the functions is not implemented (such as `psa_drv_se_mac_generate_t`), it should be set to NULL.

Driver implementers should ensure that they implement all of the functions that make sense for their hardware, and that they provide a full solution (for example, if they support `p_setup`, they should also support `p_update` and at least one of `p_finish` or `p_finish_verify`).
