Re: [dpdk-dev] [PATCH 02/51] app/testpmd: check status of getting ethdev info

["Zhao1, Wei" <wei.zhao1@intel.com>]

Hi, Ivan Ilchenko and Andrew Rybchenko

An error is cause by this patch,  it is very easy to reappear.
You only need to bind a ixgbe nic driver , and run up testpmd:
./x86_64-native-linuxapp-gcc/app/testpmd  -c 0xff -n 4 -- -i --portmask=0xff  --rxq=8 --txq=8 --port-topology=loop

Then input a rte_flow rss action cmd:
flow create 0 ingress pattern eth / ipv4 dst is 192.168.0.1 / udp / end actions rss queues 4 5 end / end
bad arguments  

so, rte_flow action rss can not be used after this patch.
