Hi,
     As I use FDIR to match and send specific flows to VF in 82599
NIC, I see the RSS hash is not consistent for a single flow. It seems
that RSS is not supported in IOV mode for 82599 NIC. I want to disable
RSS. I follow this test and use --disable-rss in testpmd to disable
RSS. But it still doesn't work. So how to disable RSS in the IOV mode
of 82599 NIC or is it a bug in the ixgbe_vf driver?

Thanks
Harold
