[dpdk-dev] [PATCH] eventdev: limit port link operation to configured queues

[Jerin Jacob]

On port_setup, the link_map is updated only
for configured number of event queues.
Limit the port_links_get scan only to configured number
of event queues. Also, Limit the port link and unlink queue
validation to configured number of event queues.

Fixes: 8ca610e0487c ("eventdev: implement the northbound APIs")
