Subject: test/distributor: fix mbuf leak on failure
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0e8704a453e5295ff9f498c6cdab7f829410ad88;p=dpdk.git

test/distributor: fix mbuf leak on failure

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.

Fixes: c3eabff124e6 ("distributor: add unit tests")
