Though the ports of XL710 are getting detected by DPDK, when I insert the above QSFP twinax cable and try to bring up the port, I get a "Operation not supported" error. When I looked further, I see that trying to bring up the port is resulting in I40E_AQ_RC_EIO and returning I40E_ERR_UNKNOWN_PHY.
Can somebody help me in understanding whether this is a genuine error? Thanks, -nagp
