run multicast daemon on vlan interface

[edrt]

Hi All,

I tried running pimd and forwarding multicast traffic on vlan interface 
with a freebsd derived kernel, but it seems that kernel failed to receive
multicast traffic on the vlan interface. 

I guess the reason partly lies in vlan_ioctl's SIOCSIFFLAGS
handler doesn't take care IFF_ALLMULTI flag and call parent 
interface's if_allmulti.

Does anyone have a success try of forwarding multicast traffic on vlan 
interface ? Or the kernel should be patched to support setting IFF_ALLMULTI
flag on vlan interface ?


Thanks
