[dpdk-dev] [PATCH v2 07/12] eal: split vector operations to architecture specific

[Zhigang Lu <zlu@ezchip.com>]

This patch splits vector operations from DPDK and push them
to architecture specific arch directories, so that other processor
architecture can implement its own vector functions to support DPDK.
