[dpdk-dev] [PATCH] app/testpmd: fix wrong return value

[Qi Zhang <qi.z.zhang@intel.com>]

The patch fix the issue that return value in parse_vc_action_rss
be overwritten unexpectly. That cause an rte_flow creation command
with rss action does not work.

For example:

testpmd> flow create 0 ingress pattern eth / ipv4 / end \
actions rss types ipv4 end / end

We will get error "Bad Agument"

Fixes: f5267e485a2a ("app/testpmd: check status of getting ethdev info")
