It would be good to include the error message in the commit log.
Also, for safety, is it better to have extra braces to cast the whole
expression, not just the sizeof, i.e.
mbuf_size = (uint32_t)(sizeof(...) + priv_size);
OK I went back and captured the original error and added it back in, and
adapted the scope of the cast as you suggested.
