Subject: [dpdk-dev] [PATCH] app/eventdev: fix port dequeue depth
 configuration
X-Mailer: git-send-email 2.14.1

The port dequeue depth value has to be compared against the maximum
allowed dequeue depth reported by the event drivers.

Fixes: 3617aae53f92 ("app/eventdev: add event Rx adapter setup")
