  Move the function pointer and port id checking macros to rte_ethdev and
rte_dev header files, so that they can be used in the static inline
functions there. Also replace the RTE_LOG call within
RTE_PMD_DEBUG_TRACE so this macro can be built with the -pedantic flag

Thanks, Declan. I'll rebase my other patchset that was very similar to this on
top of this patch and your previous one.

I suggest adding an empty line here since we're mixing code and
declarations.

> +	char buffer[vsnprintf(NULL, 0, fmt, ap)];

I forgot an extra byte for trailing '\0' in my original comment, the above
line should read:

 char buffer[vsnprintf(NULL, 0, fmt, ap) + 1];

Otherwise the last character will be missing. Did you test that function?

I didn't notice the truncation in the log message, I was just missing 
and "!" in the log message and didn't miss it. I'll push a new version 
with this fix.
