Upon running pwru --filter-trace-tc, I receive the following error:

Attaching tc-bpf progs...
failed to trace TC progs: failed to trace bpf progs: failed to rewrite bpf prog addr: rewrite constants: some constants are missing from .rodata: BPF_PROG_ADDR

This might be due to the changes to the new ebpf Variable API + some map replacements while calling func (t *tracing) traceProg(spec *ebpf.CollectionSpec, opts *ebpf.CollectionOptions, prog *ebpf.Program, n2a BpfProgName2Addr, tracingName string, ) error

This is a duplicate of #483 (error in subsequent steps to solve this issue is the same).
