[dpdk-dev] [PATCH V2] doc: add missing loopback option in testpmd guide

[Rami Rosen]

This patch adds a missing topology "loop" mode for port-topology
option in testpmd guide. The testpmd "loop" option
(PORT_TOPOLOGY_LOOP)  was added to testpmd parameter
port-topology back in 2014, but it seems that it was never added
to the testpmd guide. This patch adds it in the testpmd guide.

v2: Change "loopback" to "loop" (following Bernard review)
