Snoop issues a pile of warnings when run on an LSO-enabled NIC:

As I understand it, these are hard to avoid. It is, however, not hard
to make snoop not whinge about them.
Is this behavior useful enough that it should be kept, perhaps under
-V or -v, or is nuking it acceptable?
(and, yes, snoop's unmaintainable, etc., etc., but we're talking about
a small relief fix)
A proper fix for this would involve snoop querying the device
driver, before it opens it for sniffing packets and finding out
what capabilities it has enabled. It should also receive metadata
with the packet from the device about whether or not any given
packet is marked up for such a capability and only then ignore
problems such as you're describing.
Otherwise there is no way to distinguish a well formed packet
from a badly formed one.
