            Bug ID: 242654
           Summary: Bgx driver fails to match PHY on ThunderX after
                    r336281
           Product: Base System
           Version: CURRENT
          Hardware: arm64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: arm
          Assignee: freebsd-arm at FreeBSD.org
          Reporter: marcel at brickporch.com

Following base r336281 the onboard NIC on ThunderX boards fails to load
properly with the BGX driver (specifically on MT30-GS2, but it likely applies
to others). In particular, during boot it warns:

bgx0: Could not find matching PHY

and vnic setup via iovctl fails.

Manually removing the check in base r336281 fixes this warning and allows the
vnic setup to complete successfully.
