emit()

void EBPF::PSAArchTC::emit ( CodeBuilder * builder ) const

overridevirtual

How the structure of a single C program for PSA should look like?

1. Automatically generated comment
2. Includes
3. Macro definitions (it's called "preamble")
4. Headers, structs, types, PSA-specific data types.
5. BPF map definitions.
6. BPF map initialization
7. XDP helper program.
8. Helper functions
9. TC Ingress program.
10. TC Egress program.
