- teach tcpdump/libpcap to create code that
uses a "MEM" location which holds the nonll-offset everywhere.
- furthermore, depending on the interface, code that initializes this to
a constant (for Ethernet etc.) or to query the packet and compute the offset
- hope that the BPF bytecode optimizer knows how to make it fast in the first
Does this sound better?
