Xen users - Jul 2013 - Xen networks running in Promiscuous modes

Can I ask you a quick question? I''ve set up bridge-networking for Xen
4.1 (xen-4.1.3-25.el5.22) and networking was being done properly for Dom0 and
DomUs. However, I
noticed that Dom0 receives a lot of network interrupts or network 
packets even when they were not actually meant for either Dom0 or DomU. 
Now, here are the questions:

1. Dom0 is acting in promiscuous mode, right?

2.
 If answer to Q1 is yes, can it be stopped and yet have the bridging 
possible? If the answer is no, any idea why so many interrupts are being
 generated or if I''m missing something?

3. If I don''t want 
promiscuous mode (to avoid unnecesary interrupts), should I use Route or
 NAT option for networking? Which one is easier and do they totally 
avoid promiscuous mode?

 
Cheers...Deven.
