            Bug ID: 280110
           Summary: [dummynet] pipe config bw parameter limited to
                    4Gbits/s (due to uint32)
           Product: Base System
           Version: 15.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: history.quotas-0r@icloud.com

This is long-standing known issue.
Years ago it was lifted from 2 to 4 gbps due to transition from int32 to
uint32, but since then it stays like that.

As result, it make impossible to use number of things (for example fq_codel and
friends) on links which are faster than 4gbps.
