This last changeset for loader/net.c seems like the only valid part of this
entire patch. Please update the patch if other parts are relevant. The
layer2 and portno handling in net.c showed up in
9caaca40bcaffb502dc58659e828f97d78a2d0f8, so please make sure we don't regress
on that bug. It appears as though how we handle those values has changed,
which is fine.
