From: Andrei <andrei.gherzan@xxxxxxxxxxxxx>
The udpgro_frglist.sh uses nat6to4.o which is tested for existence in
bpf/nat6to4.o (relative to the script). This is where the object is
compiled. Even so, the script attempts to use it as part of tc with a
different path (../bpf/nat6to4.o). As a consequence, this fails the script:
Error opening object ../bpf/nat6to4.o: No such file or directory
Cannot initialize ELF context!
Unable to load program
This change refactors these references to use a variable for consistency
and also reformats two long lines.
