Subject: [PATCH v5 bpf-next 01/17] selftests: xsk: don't call worker_pkt_dump() for stats test
Date: Tue, 30 Mar 2021 00:43:00 +0200	[thread overview]
Message-ID: <20210329224316.17793-2-maciej.fijalkowski@intel.com> (raw)
In-Reply-To: <20210329224316.17793-1-maciej.fijalkowski@intel.com>

For TEST_TYPE_STATS, worker_pkt_validate() that places frames onto
pkt_buf is not called. Therefore, when dump mode is set, don't call
worker_pkt_dump() for mentioned test type, so that it won't crash on
pkt_buf() access.
