Do you know what part of the performance delta is contributed by the

On the other hand it might make sense to do this even on

Here is one idea. Do a reverse LSO, have a dynamic cache on
the network card watching saddr/daddr/sport/dport flows, and
accumulate as many in-order TCP packets as possible into one
large R-LSO frame.
This accumulation is timed out by a length and time parameter

If you have a flow cache, keyed on saddr/daddr/sport/dport
then you can keep a growing LRO limit. For example, when a
flow cache entry is created, use a LRO limit of 2
