Re: IPv6 task list

[Lloyd Parkes <lloyd%must-have-coffee.gen.nz@localhost>]

You are (probably) being affected by PR 48104.

The bridge sends the multicast NDP packets down rtk0 towards layer 1, but not 
up rtk0 towards the IP stack. That patch I included in the PR is against the 
NetBSD 6 branch.

Cheers,
Lloyd
