[dpdk-dev] pktgen wr_cksum error

[Posadas, Emerson]

Hello

I'm trying to build pktgen-v3.0.05 with dpdk 16.04 for with RTE_TARGET x86_64-native-linuxapp-gcc. Seemts that the build is failing due to an error on wr_cksum.c. Is something I can try to fix this error and build pktgen successfully? Not sure if others have had this error before.

the line is using C99 option of ‘for (int i = 0; i < X; i++) need to move the declare of the int i out to the function instead of in the for loop.
I have fixed his already, but will make a special patch to update this problem when i can.
