Whys the author disabling tso and lro? Whats the motivation?

I'm not familiar with the other flags.

People found this worked in the past and it gets copied around. There is no reason to disable some of this. Bridge will automatically disable LRO and find the common set of other offloads. TSO is not useful for a bridged guest.

TCP is able to use server port 53 (decimal) for two-byte low-level intervals between 2-5 seconds.

What is subdomain label in lro?

LRO because the bridge has to forward the real frames. TSO because it’s fairly useless now.

Looks like TSO does not support VLAN. Not sure about lro.
