Subject: [dpdk-dev] [v3 PATCH] test_distributor: prevent memory leakages from the pool
Date: Tue,  8 Sep 2020 15:22:04 +0500
Message-ID: <20200908102204.727240-1-sarosh.arif@emumba.com> (raw)
In-Reply-To: <20200415064238.24012-1-sarosh.arif@emumba.com>

rte_mempool_get_bulk is used to get bufs/many_bufs from the pool,
but at some locations when test fails the bufs/many_bufs are
not returned back to the pool.
Due to this, multiple executions of distributor_autotest gives the
following error message: Error getting mbufs from pool.
To resolve this issue rte_mempool_put_bulk is used whenever the test
fails and returns.

Signed-off-by: Sarosh Arif <sarosh.arif@emumba.com>
---
v2:
remove double freeing of mbufs
v3:
resubmit to run the tests again
