Updated by Andy Fiddaman 4 months ago
I've booted a virtual machine which uses an emulated e1000g interface under bhyve with this patch. It works and I was able to transfer data across the network as before.
In addition to doing DNS lookups and transfers with SCP, I also ran
iperf in UDP and TCP modes to send sustained traffic and the performance was the same as before the patch.
