Attempting to configure SR-IOV via iovctl returns = an EINVAL (Invalid argument) error, even though the device advertises SR-IOV capability and the driver=E2=80=99s iov_init path succeeds. This seems to be a limitation or missing support in the PCI SR-IOV layer ra= ther than a driver issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
