On-topic:

Anyone working on or testing network device drivers should be using
IPv6. IPv6 will exercise code paths and network behaviour that Legacy IP
rarely does, in particular using multicast to do neighbour discovery.
And on wireless networks when multicast will be handled differently by
the AP, that makes more difference than on wired where it's mostly the
MAC filters that get neglected.

I've seen a number of broken drivers because their authors were only
testing with Legacy IP and not IPv6.

It's not hard to set up IPv6. Larry, if you need any pointers I'd be
more than happy to help.
