[dpdk-dev] [PATCH 19.11 V3 02/12] ethdev: fix description of tx descriptor status

From: Olivier Matz <olivier.matz at 6wind.com>
The API comment of rte_eth_tx_descriptor_status() was incorrect. The
reference descriptor (when offset = 0) is not where the next packet
will be sent, but where the latest packet has been enqueued.
Fixes: 52f5cdd2e897 ("ethdev: add descriptor status API")
