I suspect that my NIC is working in hybridization mode?

Hi, all:

The physical network interface card should drop the packets if it doesn't match the MAC address of the NIC. In my PC, however, the packets which shoud be dropped trigger the interrupt function of my own driver and are recieved as skb to be transfered to the upper layer!

Why? How should I do to filter the packets at physical layer? I suspect that my NIC is working in hybridization mode?

Notes: my platform is linux 3.0.4 on x86.

Excuse me: not "hybridization mode" but "promiscuous mode"!

Being a hardware thing what you want depends on the hardware. Read up on the chipset involved if you can.
