Even after setting RSS key to desried value , i don’t see correct behaviour,
also i see the rss hash key being restrored to some value everytime i start and stop testpmd . is this expected ?

is the rss key even taking into effect ?

Could you please help me configure me symmetric RSS on VF using DPDK
