Does the full tcpip stack support multicasting now in patch B?

Yes. Start your driver with ‘multicast=1’:
slay io-net
io-net -d multicast=1 -ptcpip
ifconfig en0 <ip_addr>
route add default <gateway_ip_addr>
After the above, ‘ifconfig en0’ should show the MCAST flag set.

I added ‘multicast=1’ when starting the el900 driver and now I get an
error 249 Can’t assign requested address from setsockopt(). I am using
address 225.0.0.37. This address is in the correct range isn’t it?

Also note that this has/will change in the 6.1 release. All drivers that
have multicast support will have it enabled by default and will honour
the IFF_MULTICAST flags (from ifconfig and getsockopt). You will be able
to force the device to NOT use multicast by giving the single command
line option “nomulticast” like this…
io-net -d tulip nomulticast -p tcpip
