ne3 vs. ne0

[Rob Sessink <rob_ses_(_at_)_web_(_dot_)_de>]

After compiling a new kernel with support for usb & umass,  my ne2000 
clone card changed from:
	"ne3 at pci0 dev 10 function 0 "Compex Ethernet" rev 0x0a: irq 9"
to
	"ne0 at pci0 dev 10 function 0 "Compex Ethernet" rev 0x0a: irq 9"
this messed up my routes and dns config. In my kernel config i have the 
following lines
'#ne0     at isa? port 0x240 irq 9                # NE[12]000 ethernet
'#ne1    at isa? port 0x300 irq 10               # NE[12]000 ethernet
'#ne2    at isa? port 0x280 irq 9                # NE[12]000 ethernet
ne*    at isapnp?                              # NE[12]000 PnP ethernet

I was curious so i changed my kernel config to this and compiled a new 
kernel:
ne0     at isa? port 0x240 irq 9                # NE[12]000 ethernet
'#ne1    at isa? port 0x300 irq 10               # NE[12]000 ethernet
'#ne2    at isa? port 0x280 irq 9                # NE[12]000 ethernet
'#ne*    at isapnp?                              # NE[12]000 PnP 
ethernet

Now this line showed up at boot:
ne1 at pci0 dev 10 function 0 "Compex Ethernet" rev 0x0a: irq 9

Can someone explain how this happens ? 
Since the new kernel i haven't gotten anymore timeouts and ring 
overflows for the ne? card.
