Multicore test

[alexsalig]

I want to test multi-core version of ipaugenblick. I found 3 multi-core branches, but can't run any of them:

• mulitcore branch: give me following error:
  ipaugenblick-multicore/dpdk-1.6.0r2/x86_64-default-linuxapp-gcc/build/lib/librte_eal/linuxapp/kni/ixgbe_ethtool.c:2899:2: error: implicit declaration of function ‘SET_ETHTOOL_OPS’ [-Werror=implicit-function-declaration] SET_ETHTOOL_OPS(netdev, &ixgbe_ethtool_ops);
• mulitcore2 branch: give me following error:
  ipaugenblick-multicore2/stack_and_service/porting/app_glue.c:416:26: error: subscripted value is neither array nor pointer nor vector app_glue_periodic_called[rte_lcore_id()]++;
• mulitcore3 branch: give me following error:
  ipaugenblick-multicore3/stack_and_service/specific_includes/net/sock.h:1294:57: error: subscripted value is neither array nor pointer nor vector ret = res_counter_charge_nofail(&prot->memory_allocated[rte_lcore_id()],

Hi Alex,

multicore3 is the latest branch. However, there are some compiling issues. Can you do the following changes to the branch you clone
chaudhryusama@f785f94
This will fix the error you are facing during compilation. By the way this branch is still a work in progress.

Thanks. Now, I can compile the project, but when I run following command:

root@debian:/ipaugenblick-multicore3# /usr/bin/ipaugenblick_srv -c 1 -n 1 -d /ipaugenblick-multicore3/dpdk-2.0.0/x86_64-native-linuxapp-gcc/lib/librte_pmd_e1000.so -- -p 0

I get this error:

I test it with ixgbe network interface, but get the same error.
