Hello, I have an application that processes packets received by an Intel XXV710 NIC via the i40e PMD in DPDK. I need all MAC control frame packets to be passed to the application as regular packets, but I have been unable to configure the device to do this successfully, all control frames seem to be consumed by the hardware and do reach the application queues at all. Referencing the datasheet for this card and the i40e PMD, I need to enable MAC control frame forwarding.
I have tried to configure the card using the rte_eth_dev_flow_ctrl_set call with the following settings in the struct rte_eth_fc_conf: .mode = RTE_FC_NONE; .high_water = 0; .low_water = 0; .pause_time = 0; .send_xon = 0; .mac_ctrl_frame_fwd = 1; .autoneg = 0; The call returns successfully yet checking with rte_eth_dev_flow_ctrl_get shows that the value for .mac_ctrl_frame_fwd is still zero and I cannot see control frames in my application. How can I configure this card to pass these frames? Thanks, Paul.
