IPv6 neighbor discovery uses various multicast addresses to send the request and receive the response. For neighbor discovery to work properly in U-boot the Ethernet device needs to support joining/leaving various multicast groups or it needs to support multicast/promiscuous mode. For the sake of simplicity the latter approach has been taken.

Signed-off-by: Chris Packham judge.packham@gmail.com --- Drivers that support multicast reception have it enabled/disabled with CONFIG_MCAST_TFTP. It wouldn't be too hard to create a separate CONFIG_MCAST that is selected by enabling CONFIG_MCAST_TFTP or CONFIG_NET6 but for now I want to concentrate on getting the rest of the IPv6 code in good shape.
