Hi!

	I want to write a function to set a multicast filter in my
Ethernet controller driver. But as seen in some driver in such a
function the interface flags such as IFF_ALLMULTI, IFF_PROMISC are
checked and corresponding action is taken.

Can anyone please tell me that where these flags are being set for an
interface?
I mean if I have the following options with my controller

        1. Reject packets CAM recognizes
           accept other.
	  2. Broadcast accept
	  3. Multicast accept
	  4. unicast accept=20

How do I decide which one to enable when that is who will set the
corresponding flags in the ifnet structure?

Thanking you in advance

Regards
