Initialvfs
WebbI don't see the point of reading TotalVFs in sriov_init() and reading InitialVFs in sriov_enable(). If we read them both in sriov_init(), I don't think we'd have this problem of sriov_enable() returning -EIO. 2) To work around this non-compliant device, we should read InitialVFs and TotalVFs after setting the ARI bit.
