Hello ,

We have 30 VF's  and  first 15 VF's are handled by DPDK i.e. bound to igb_uio and PF is boud to ixgbe driver.

I am trying  to set Flow Control parameters for a VF/port using rte_eth_dev_flow_ctrl but it always returns error code -95.

Same error code is returned by tetspmd application as well.

"testpmd> set flow_ctrl rx off 0
cannot get current flow ctrl parameters, returncode = -95" .


If Any one of you are succeeded in setting  flow control parameters for a VF using DPDK 1.7 , please help me .

I was expecting  at least testpmd application should work  with flow control set API, but it is not the case.

I have tried to switch of Flow Control using  ethtool for PF  , no error message,  but its not reflecting the changes.


Thanks and Regards,
Sharat Bhat
