Yes, to determine the packet is a LSO one, snoop needs to get the meta

Seeing as snoop currently doesn't know the MTU
What makes you say that?
Doesn't dlpi_info() return that in snoop_capture.c`open_datalink?
Or am I missing something?
It's di_max_sdu that gets used, not mtu_size, throughout the code...
This, however, seems a bit... bogus...
/* for backward compatibility, allow known interface mtu_sizes */
if (interface->mtu_size > dlinfo.di_max_sdu)
dlinfo.di_max_sdu = interface->mtu_size;
