Bug ID: 289028
Summary: FreeBSD PCI SR-IOV layer rejects VF creation on
bonded/aggregate PFs
Product: Base System
Version: 15.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
When a Broadcom NetXtreme-E NIC is configured in aggregate mode (multiple
physical ports combined into a single PCI PF, presenting a single high-speed
interface, e.g., 200G), the FreeBSD PCI SR-IOV framework fails to create
Virtual Functions (VFs). Attempting to configure SR-IOV via iovctl returns an
EINVAL (Invalid argument) error, even though the device advertises SR-IOV
capability and the driver’s iov_init path succeeds.
This seems to be a limitation or missing support in the PCI SR-IOV layer rather
than a driver issue.
