Subject: [dpdk-dev] [PATCH] app/test: fix refcnt_mbuf_ring size
Date: Mon, 18 Jul 2016 11:25:54 +0530 [thread overview]
Message-ID: <1468821354-23612-1-git-send-email-jerin.jacob@caviumnetworks.com> (raw)
rte_ring_create expects the size of the ring to
be a power of 2. REFCNT_RING_SIZE value is not
power of 2 in-case if RTE_MAX_LCORE == 96.
Fix it by aligning the size to next power of 2 value.
Fixes: af75078f ("first public release")
