+ * The hns3 VF PMD driver depends on the hns3 PF kernel ethdev driver,
+ * so there are some features for promiscuous/allmulticast mode in hns3
+ * VF PMD driver as below:
+ * 1. The promiscuous/allmulticast mode can be configured successfully
+ * only based on the trusted VF device. If based on the non trusted
+ * VF device, configuring promiscuous/allmulticast mode will fail.
+ * The hns3 VF device can be confiruged as trusted device by hns3 PF
+ * kernel ethdev driver on the host by the following command:
+ * "ip link set <eth num> vf <vf id> turst on"
+ * 2. After the promiscuous mode is configured successfully, hns3 VF PMD
+ * driver can receive the ingress and outgoing traffic. In the words,
+ * all the ingress packets, all the packets sent from the PF and
+ * other VFs on the same physical port.
+ * 3. Note: Because of the hardware constraints, By default vlan filter
+ * is enabled and couldn't be turned off based on VF device, so vlan
+ * filter is still effective even in promiscuous mode. If upper
+ * applications don't call rte_eth_dev_vlan_filter API function to
+ * set vlan based on VF device, hns3 VF PMD driver will can't receive
+ * the packets with vlan tag in promiscuoue mode.
