Before the hw change speed successfully, the driver get old old speed from hw by timer task. After reset, the previous speed is config to hw. As a result, the new speed is configed successfully but lost after PF reset.

In most time, it works fine. But there is a time window before the service task shceduled and net device being registered.

After imp reset command is executed, PF status changes to down, and PF will query link status and updates port information from firmware in a periodic scheduled task. However, there is a low probability that port information is updated when PF is down, and then PF link status changes to up. In this case, PF synchronizes incorrect rate and duplex mode to VF.

And dev->is_busmaster is set to 0 in pci_disable_device. Signed-off-by: Cai Huoqing <cai.huoqing@linux.dev> Signed-off-by: David S.

VF keep sending the mailbox per 2 seconds. Once PF lost the mailbox for more than 8 seconds, it will regards the VF is abnormal, and stop notifying the state change to VF, include link state, vf mac, reset, even though it receives the KEEP_ALIVE mailbox again. It's inreasonable. This patch fixes it. PF will record the state change which need to notify VF when lost the VF's KEEP_ALIVE mailbox. And notify VF when receive the mailbox again. Introduce a new flag HCLGE_VPORT_STATE_INITED, used to distinguish the case whether VF driver loaded or not. For VF will query these states when initializing, so it's unnecessary to notify it in this case.
