Description

Add packet decoder for 802.1BR E-tag. See the pcaps attached to the ticket. You can use setup/setup-decoder.sh to bootstrap a new packet decoder. The minimal functionality should be that the decoder gets called when the ethernet header has a ethertype indicating this header type (see DecodeNetworkLayer, and then the header should be decoded to find the next ethertype, for which the correct packet decoder should be called as well then.

Wireshark is a useful tool to inspect the pcaps and see how the headers are aranged.

As part of this ticket Suricata-Verify tests should be created using both pcaps.
