(In reply to Bob Smith from comment #42)
The ideal number will vary by card (model/brand/...)
We only ever experienced the watchdog(8) problem on
any of our RealTek cards on FreeBSD-11.x. We have *not*
needed to "tune" these cards for watchdog on 12, or 13.
The following 2 servers are on 12, and use the same NIC
but, as you can see, have 2 different values. We did
NOT adjust them from their default values.

kern.ipc.nmbjumbop: 508829
kern.ipc.nmbclusters: 1017660

kern.ipc.nmbjumbop: 125487
kern.ipc.nmbclusters: 250974
