Subject: [dpdk-dev] 1.7.0 release failed to compile on linux

Hi,

I got the following error when I tried to compile 1.7.0 release tarball 
on a Linux box (Ubuntu 12.04/kernel=3.13.0-32-generic, gcc=4.6.3):

Apparently the version check around 'skb_set_hash' in kcompat.h failed 
for some reason. To work around it, I temporarily commented out that 
'skb_set_hash' definition code and rte_kni complied fine. But it failed 
again in librte_pmd_ixgbe:

My CPU is the older Intel C2D E6550 which does not have sse4.2/sse4.1 
support. Is there a way to work around this?
