[Bug 273372] SR-IOV Networking in Bhyve Causes Chelsio T520-SO-CR to Fail on Host, Kernel Panic if Reset

--- Comment #7 from Mark McBride <mark@markmcb.com> ---
Still present 14.0-RC3. For clarity, the kernel issue only happens if I try to
reset the PCI device with devctl AFTER the card/driver fails.

To rule out the mobo/processor being the culprit on the the PCI bus, I have
tested with a Supermicro X11SSM-F and Intel Xeon E3-1275 v6, and with a
Supermicro X12STH-F and Intel Xeon E-2388G. Both fail with the same symptoms.
Driver loads, device looks active in the VM. Can't ping anything, dhclient does
nothing, and then after a minute or so the whole card fails (both physical
ports, not just the one I'm using for SR-IOV).
