The significance is that the kernel determines the eth* name order. Right now, you are lucky in that the order is what you think it should be, but if something changes in the kernel causing your cards to be initialized in a different order, you will not be allowed to swap them around in the eth* name space, e.g. eth1 can't become eth0 or visa versa. That is why it is recommended that you use something like net0, net1, etc for your interface names. William
