two net_device ?

["??" <seong@xxxxxxxxxx>]

Hi, there.

I implemented 32 pseudo interface(eth1 ~ eth32) using a module.
When I up the interfaces using "ifconfig eth1 xx.xx.xx.xx" command,
there are two "eth1" interface. Before I up the interfaces, there is a "eth1" 
interface.
I can't find what thing goes wrong.

For test, I made just 2 pseudo interface using same mechanizm. then
above problem doesn't occur.

any suggestion, thanks..
I use 2.4.17 kernel.
