[dpdk-dev] [PATCH 1/2] app/testpmd: fix empty list of RSS queues for flow

Since the commit referenced below, specifying a RSS action without any
queues (e.g. "actions rss queues end / end") does not override the default
set automatically generated by testpmd.

In short, one cannot instantiate a RSS action with 0 target queues anymore
in order to determine how PMDs react (hint: this is currently undocumented
so they may reject it, however ideally they should interpret it as a
default setting like for other fields where empty values stand for
"defaults".)
