[dpdk-dev] [PATCH v2 14/39] examples/ip_reassembly: convert to new ethdev offloads API

[Shahaf Shuler]

Ethdev offloads API has changed since:

commit ce17eddefc20 ("ethdev: introduce Rx queue offloads API")
commit cba7f53b717d ("ethdev: introduce Tx queue offloads API")

This commit support the new API.
