So, style bugs and a memory copy in handling arp packets is enough to keep
an ancient 'known issue' and a compile failure fix out of the tree?
I mean, look at the current code. Unless I mis-understand, someone could
send a bogus arp packet with hw-len field set to something large and you
are going to buffer overflow, allowing someone to own a process with root
privileges, or at least crash xorp horribly.
