How to get the number of Multicast/Braodcast packets from Kernel

[Rangarajan Krishnan]

Hi,
The file /proc/net/dev has info on Unicast packets (In/Out,
Error/Dropped etc). I need information on where to find the same
(In/Out, Error/Dropped etc) for Multicast and Broadcast Packets. Can
anyone help me in this?
Thanks in advance.
