Subject: test/ring: do not mask result of enqueue or dequeue
X-Git-Tag: spdx-start~2133
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=effd92b96a978fa5d08167bd08e5cc11f6982f79

test/ring: do not mask result of enqueue or dequeue

The define RTE_RING_SZ_MASK is the maximum size supported by the
rte_ring. The size is checked at ring creation.

There is no reason today to mask the result of
rte_ring_sp_enqueue_burst() or rte_ring_sc_dequeue_burst() with this
value. The flag RTE_RING_QUOT_EXCEED was previously included in the
returned value but it was removed in
commit 77dd3064270c ("ring: remove watermark support").
