Well, there is no sign of package loss on tcp during few simple tests,
but udp packages, which length is 4096 are still broken, making DNS
unusable. Small packages, SOA requests, for example, are working j

Thanks. I'll test it as soon as it will be in mainline release (we've already

I'm confirming, that this happens only when macvlan's are onto dummy net
device. In case of some physical interface under macvlan there is no
