Errr, sir... something goes wrong here.
As per your "/etc/udev/rules.d/70-persistent-net.rules":
eth0 -> realtek
eth1 -> 3com
But that is not what dmesg says above.
Also, there is no "link up" or "link down" for eth1 but *both" eth0 going
up. Not sure how to interpret that.

I don't think this issue can have any relation with ipv6 :-?.
How about your "/etc/network/interfaces"?
Besides, you can make a quick probe by disabling "eth1" and test if the
network works as expected ("ping" et al) and then disable "eth0" and
perform the same test. I mean, test the network adapters "separately".
