Don't define them here. Transport header file is responsible for defining it.
The same for NRF_RPC_TR_AUTO_FREE_RX_BUF.

This is ifdef def, so if transport have not defined anything the values of macros are set to default.

user_data is not longer needed. Right?

We are using SM IPT module, so we can use its name instead of just shared memory.

Maybe it is better to explain this #ifdef, because it is not obvious.

/* If nrf_rpc_tr_alloc_tx_buf is a macro, put it directly, because it may allocate memory on stack. */

Why is this in nrfxlib and not in sdk-nrf/lib ?

I don't see any prebuilt libraries in this PR, which is usually the case for nrfxlib libs.

Why is this in nrfxlib and not in sdk-nrf/lib ?

I don't see any prebuilt libraries in this PR, which is usually the case for nrfxlib libs.

@tejlmand, just FYI, the nrfxlib is not only for prebuild libraries. It is place for modules that are independent from Zephyr/NCS, so user can take some module from nrfxlib and use it e.g. in FreeRTOS or baremetal. Other example is nrf_rpc in this repo. If this PR will be reopen then it will be exactly for such case.

Edit: After reconsideration, I see now that it is not very clear if nrfxlib is only for prebuild libraries or not. I see no better place to put this PR (and nrf_rpc which is similar case), so I am still thinking that this RP should go into nrfxlib if reopened.
