[dpdk-dev] [PATCH] examples/ip_pipeline: fix buffer not null terminated

[Jasvinder Singh <jasvinder.singh@intel.com>]

The destination string may not have a null termination if
the source string's length is equal to the sizeof(link->name).

Fix by replacing strncpy with strlcpy that guarantees NULL-termination.

Coverty issue: 272594
Fixes: 133c2c6565d6 ("examples/ip_pipeline: add link object")
