Comment 18 for bug 1436330

My understanding was that there would be packet loss all the time without the patches applied, due to packets being sent in a round-robin fashion between two links to the same default gateway.

This said, I'm able to reproduce the apparent "packet loss", but I say apparent here because it seems to be an issue with ping (or, the kernel does something special, doesn't understand packets coming in to an interface it doesn't expect perhaps), not with the actual packets.

I've been able to observe traffic going out to my default gateway and coming back, with no interruption, using tcpdump:
sudo tcpdump -i any icmp

I don't think at this point we're working with anything different from how it was in Trusty, but just to be on the safe side I'll test that out to confirm we did get the same behavior.
