flow_dissector: Add PPPoE dissectors
Allow to dissect PPPoE specific fields which are:
- session ID (16 bits)
- ppp protocol (16 bits)
- type (16 bits) - this is PPPoE ethertype, for now only
ETH_P_PPP_SES is supported, possible ETH_P_PPP_DISC
in the future
The goal is to make the following TC command possible:
# tc filter add dev ens6f0 ingress prio 1 protocol ppp_ses \
flower \
pppoe_sid 12 \
ppp_proto ip \
action drop
Note that only PPPoE Session is supported.
