Subject: mempool: use specific macro for object alignment
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=b32037f7ef384e664200baedbb4aebe9a216f73d

mempool: use specific macro for object alignment

For consistency, RTE_MEMPOOL_ALIGN should be used in place of
RTE_CACHE_LINE_SIZE. They have the same value, because the only arch
that was defining a specific value for it has been removed from DPDK.
