[dpdk-dev] [PATCH] ixgbe: Reduce compilation to only require sse3 intrinsics

[Neil Horman <nhorman@tuxdriver.com>]

ixgbe was failing to build in the default configuration because it required
sse4.2 intrinsics, and the default config doesn't support more than sse3.
Modify the pmd so that only sse3 intrinsics are pulled in and used.
