            Bug ID: 247111
           Summary: pxeboot very slow with i219LM
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: michel.popp at hetzner.com

I have a problem with the binary PXEBOOT and the nfs / diskless setup setup.
Unfortunately, PXEBOOT loads the kernel with i219LM NICs very slowly. It takes
up to 15 minutes to load the kernel. Compared to a Realtek or i210 / i211 NIC,
it only takes 2 minutes to load the kernel.
