Good point, I didn't notice it was coming from there.

I don't think that's needed: 'net/forwarding/lib.sh' is far from being
compatible with 'errexit', please look at all the utilisations of '$?'.

For 'net/lib.sh', that's different: some functions explicitly check for
'errexit' support. If I'm not mistaken, I fixed the only place where it
was not compatible with 'errexit'.
