Subject: event/dlb2: fix array overflow
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=897e2aab031bbd2c9a825b99fb08d6cc087a0e93;p=dpdk.git

event/dlb2: fix array overflow

This commit fixes a segfault that resulted from reading
beyond the end of the port_cos array. The root cause was using
the DLB num ports define instead of the eventdev num ports define.

Fixes: bec8901bfe9f ("event/dlb2: support ldb port specific COS")
