Wireshark-dev: [Wireshark-dev] Dissector for link layer to run before ethernet one

Hello all,

I have some capture files with packets encapsulated under ethernet. But
these packets have a short header before the mac addresses and I am
trying to write a dissector that would run before the ethernet one,
parse the header and then call the ethernet dissector to continue parsing
the rest of the packet.

I was not able to find any example of this being done and I guess it would
involve changing the entry in the wtap_encap table to replace the eth
dissector.

Any ideas on how this could be done?

All the best,

Mihai
