If by arp spoofing you mean receiving arp replies from multiple sources and
trusting all of them, then I haven't seen anything.  I speaking from
experience as having been bitten by this in earlier kernels (2.6.15 and 2.6.17),
it's a pita to diagnose in a large environment.

I don't know the history as to why nothing has has been done.
