Hello,

The SMP transport API, used by MCUmgr to process requests, drops zephyr_ prefix from interface functions and type definitions; this means that

all zephyr_smp_* functions/types are now smp_* types.

The API is not officially stable, or even listed here https://docs.zephyrproject.org/latest/develop/api/overview.html#api-overview, but it has been in Zephyr for a long time and

could  have been used by some out-of-treen transports, that will now get broken.

The change can be reviewed here:

Hello,

I have posted missing RFC for the change here https://github.com/zephyrproject-rtos/zephyr/issues/49962 and extended it to cover removal of the zst parameter from zephyr_smp_transport_out_fn.
PRs, which  implement the RFC,  are here: https://github.com/zephyrproject-rtos/zephyr/pull/49528 and here https://github.com/zephyrproject-rtos/zephyr/pull/49527.

Best regards,
Dominik Ermel
