According to the protocol of PCIe, FLR to a PF device resets the PF state as well as the SR-IOV extended capability including VF Enable which means that VFs no longer exist. When PF device is in FLR reset stage, at this time, the register state of VF device is not reliable, so VF device's register state detection is not carried out in PF FLR. In this case, we just ignore the register states to avoid accessing nonexistent register and return false in the internal function named hns3vf_is_reset_pending to indicate that there are no other reset states that need to be processed by PMD driver.
