It can be enabled\n using bnxt devargs. For ex: \"-w 0000:0d:00.0,host-based-truflow=1”.\n \n+Notes\n+-----\n+\n+- On stopping a device port, all the flows created on a port by the\n+  application will be flushed from the hardware and any tables maintained\n+  by the PMD. After stopping the device port, all flows on the port become\n+  invalid and are not represented in the system anymore.\n+  Instead of destroying or flushing such flows an application should discard\n+  all references to these flows and re-create the flows as required after the\n+  port is restarted.\n+\n+- While an application is free to use the group id attribute to group flows\n+  together using a specific criteria, the BNXT PMD currently associates this\n+  group id to a VNIC id. One such case is grouping of flows which are filtered\n+  on the same source or destination MAC address. This allows packets of such\n+  flows to be directed to one or more queues associated with the VNIC id.\n+  This implementation is supported only when TRUFLOW functionality is disabled.\n+\n+Note: A VNIC represents a virtual interface in the hardware. It is a resource\n+in the RX path of the chip and is used to setup various target actions such as\n+RSS, MAC filtering etc. for the physical function in use.\n+\n+Virtual Function Port Representors\n+----------------------------------\n+The BNXT PMD supports the creation of VF port representors for the control\n+and monitoring of BNXT virtual function devices. Each port representor\n+corresponds to a single virtual function of that device that is connected to a\n+VF. When there is no hardware flow offload, each packet transmitted by the VF\n+will be received by the corresponding representor. Similarly each packet that is\n+sent to a representor will be received by the VF. Applications can take\n+advantage of this feature when SRIOV is enabled. The representor will allow the\n+first packet that is transmitted by the VF to be received by the DPDK\n+application which can then decide if the flow should be offloaded to the\n+hardware. Once the flow is offloaded in the hardware, any packet matching the\n+flow will be received by the VF while the DPDK application will not receive it\n+any more. The BNXT PMD supports creation and handling of the port representors\n+when the PMD is initialized on a PF or trusted-VF. The user can specify the list\n+of VF IDs of the VFs for which the representors are needed by using the\n+``devargs`` option ``representor``.::\n+\n+  -w DBDF,representor=[0,1,4]\n+\n+Note that currently hot-plugging of representor ports is not supported so all\n+the required representors must be specified on the creation of the PF or the\n+trusted VF.\n+\n Application Support\n -------------------\n \n",
