libnfnetlink has good doxygen documentation but there was no output when
doxygen was run.
Patch 1/1 fixes that,
but on rebuilding there were a number warnings of the form:
right-hand operand of comma expression has no effect [-Wunused-value]
*This was not introduced by patch 1/1*
Instead, it is caused by the definition of "prefetch" in include/linux_list.h:
#define prefetch(x) 1
the Linux kernel has:
#define prefetch(x) __builtin_prefetch(x)
I see 3 ways to get back to a clean compile:
1. Suppress the warnings with a pragma
2. Reinstate the Linux definition of prefetch
3. Expunge prefetch from the header file
I have made all 3, please indicate which one you'd like.
1. & 2. are 1-liners while 3. is multiline.
3. allows of extra simplifications, such as defining a macro in a single
line or fewer lines than before. In some places I could also delete the fragment
"&& ({ 1;})".
