When we setup the network interface, add predefined IPv6 multicast
groups into the network interface. When interface is taken down,
then leave all the multicast groups that joined.
See RFC 4291 ch 2.8 for details.

If we receive lot of packets, it might happen that we exhaust
all the DATA buffers in the system. This would prevent from
us sending anything to the network.
Change this by splitting the DATA buffer pool into RX and TX
parts. This way RX flooding cannot consume all DATA buffers
that needs to be sent.
