Linux Ethernet Bridging - Aug 2009 - [Bridge] bnx2 doesn't transmit BPDU or Blade switches don't forward them?

Hi,
 I have two Blades in one enclosure. They receive the same VLAN trunk
to bridge the VLANs and I want to have two bridges enabled in each
server. I've configured the bridge and enabled STP but I don' t see
the BPDU multicast incoming from the interface (I see the outging
packets).

Blade MACs are:
00:23:7d:37:08:78
00:23:7d:37:1a:82

Is there some issue with bnx2 or Blade switches and Linux bridge?
