I have a problem that on a ThinkPad T430s, IPv6 neighbor solicitations
do not arrive on the wireless interface. I can see that my wireless router
send them, but for some reason they don't arrive.

IPv6 works fine on 14.3.

Please let me know if more information would help. I'll try upgrading
to BETA4.
