I want to add ipv6 support on my ecos board. It requires
CYGINT_IO_ETH_MULTICAST , but I can't find it in 'common ethernet
support' of 'I/O sub-system' , can anyone help me? Thanks.

In order to support IPV6, the ethernet interface you are using must
support multicast. Probably the ethernet driver you are using does not
have multicast, so is not implementing the interface
CYGINT_IO_ETH_MULTICAST.
