Hi,
I have some problems in running netmap pkt_gen, the receiving mode seems
okay, but the sending mode will cause segmentation fault.
when i compile pkt_gen.c, it warns three times, in Makefile with CFLAGS
-Werror, so the warning is treated as error, so i deleted -Werror, then it
can make pkt_gen binary file, but int can't run successfully.
I did it on x86 64 bit Linux
In file included from pkt-gen.c:43:0:
pkt-gen.c: In function 'main':

Did it happen to you?
