[dpdk-dev] [PATCH] examples/netmap_compat: fix infinite loop

[Michal Kobylinski]

Fix issue reported by Coverity.

Coverity ID 30701: Infinite loop: The loop does not have a normal
termination condition, so will continue until an abnormal condition
arises. In rte_netmap_poll: Infinite loop with unsatisfiable exit
condition.

Fixes: 06371afe394d ("examples/netmap_compat: import netmap compatibility 
example")
