You will have to be careful when doing this. diag_printf() uses a very
simple polled IO, blocking serial device driver. The idea is that it
should always work, in any context. So you can do a diag_printf() in
an ISR or a DSR, not just a thread. It is also guaranteed the output
will be out the serial port before diag_printf() returns.
If you somehow modify diag_printf to send over a network stack it is
unlikely you can keep these properties. I would suggest you look at
adding a standard syslog interface, eg:
#include <syslog.h>
void openlog(const char *ident, int option, int facility);
void syslog(int priority, const char *format, ...);
void closelog(void);
#define _BSD_SOURCE
#include <stdarg.h>
void vsyslog(int priority, const char *format, va_list ap);
and don't modify diag_printf().
