It could be the switch? Some switches require configuring the port as monitor
mode (othewise they do MAC filtering).

I have a machine with:
03:02.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02)
        Subsystem: IBM: Unknown device 026f
        Flags: bus master, 66Mhz, medium devsel, latency 64, IRQ 28
        Memory at c0200000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: [40] PCI-X non-bridge device.
        Capabilities: [48] Power Management version 2
        Capabilities: [50] Vital Product Data
        Capabilities: [58] Message Signalled Interrupts: 64bit+ Queue=0/3 Enable

but haven't tried bridging with it.
