[dpdk-dev] [PATCH 13/13] examples: overhaul of ip_reassembly app
Anatoly Burakov
anatoly.burakov at intel.com
Wed May 28 19:32:47 CEST 2014
New stuff:
* Support for regular traffic as well as IPv4 and IPv6
* Simplified config
* Routing table printed out on start
* Uses LPM/LPM6 for lookup
* Unmatched traffic is sent to the originating port
