2.3.0.1 and later drivers and firmware add MAC reuse feature, when the driver is compatible with firmware version 2.3.0.0 and before, if the ip link command is used to configure the MAC and VLAN for the VF, it will cause the VF network anomaly.
To solve this problem, the driver obtains the function capability from the firmware when loading, and determines whether to support MAC reuse for different processing.

VF does not switch interrupts on the virtual machine. If the hardware sends the entire tx queue packets between tx_poll processed all the packets and calling napi_complete, it will cause the hardware to no longer report the interrupt, napi will not be called again, and driver unable free up tx resources. Eventually, the queue is full and packets cannot be sent.
By calling tx_poll again before napi_complete, to ensure that the queue resources can be released in time.
When clearing queue resources during ifconfig down processing, determine whether the packet has been sent more accurately by judging hardware CI and software PI.

After the user executes the reboot -f command, the kernel restart process is followed. One of the steps is device shutdown. The main process of reboot is stuck in the hns3 NIC shutdown callback process and stuck in the kernel's rtnl lock. The reason why the card is locked in the rtnl is that the system sar, ip, ethtool and other commands are acquiring the information on the network card through the sys fs interface. Rtnl lock is required before accessing the device. When accessing the hinic network card, first lock the rtnl, and then transfer to the hinic callback hinic_get_link_ksettings to get the data. The network card sends a request to the chip through the assembly command and waits for the chip to respond. When the device is shut down, the chip has been shut down and cannot respond. The driver can only wait for a timeout (synchronously wait for 10s), then the rtnl lock will be held for 10 seconds before releasing.
The hinic driver sets the card to the absent state in the shutdown interface, forcing all commands not to be sent to the chip to avoid the command being stuck for a long time.

When there are multiple priority packets in a tx queue in 1822, the out-of-sequence of the sent packets will cause data inconsistency. When DCB is enabled and Layer 2 forwarding is configured, when the receiving vlan device is configured with ingress_map, the priority of skb may be mapped to a non-zero value. The hinic driver first selects the queue through skb-> priority, but the priority is fixed to use vlan priority. As a result, there may be multiple priorities for the same tx queue. Therefore, the driver is modified to only select the queue through the VLAN priority.

It is not allowed to send commands to the firmware during the firmware upgrade process, and some commands are not retried during the VF loading process, causing the loading to fail. Troubleshoot and modify commands that have not been retried to ensure that the driver can continue to load after the hot upgrade is complete.
