[CentOS] ifconfig showing same mac for 2 nics in same bond

Hi all,

I just noticed that my two nics that are bonded via mode 0 are showing  
the same mac addy in ifconfig.

Is this normal?

In syslog I keep getting;
kernel: pbond0: received packet with  own address as source address

Some guidance is appreciated before I dive in and troubleshoot.

If I don't list the mac addy in my ifcfg-th# files, only one of the 2  
nic comes up during boot.
