[dpdk-dev] [PATCH 2/2] app/testpmd: add set topology on the fly command

Wed May 9 14:34:39 CEST 2018
Change the forward topology while testpmd is running,
the valid topologies are loop, paired, chained & custom.
When the forward topology is changed on the fly, all
the ports will restore their active status.
usage:
testpmd> set fwd-topo paired|chained|loop|custom
