[dpdk-dev] [PATCH] examples/eventdev: fix build with GCC < 5

[Thomas Monjalon]

Some errors were seen with GCC 4.8 and 4.9.
It looks to be a bug fixed in GCC 5.

examples/eventdev_pipeline/pipeline_worker_generic.c:474:4: error:
missing initializer for field 'queue_id' of 'struct <anonymous>'

examples/eventdev_pipeline/pipeline_worker_generic.c:475:3: error:
missing initializer for field 'priority' of 'struct <anonymous>'

examples/eventdev_pipeline/pipeline_worker_tx.c:630:2: error:
missing initializer for field 'queue_id' of 'struct <anonymous>'

The workaround is to not use initializer statement,
but to use memset and standard assignment.
