[uml-user] tap interface doesn't work

[matthew <ma...@de...>]

Hi,

I'm not sure if this is a UML problem or a tun/tap problem, so I've sent
this to both lists.

I get this error:

Configuring eth0:
ifconfig eth0 10.100.10.2 broadcast  netmask 255.255.255.0
tuntap_open_tramp failed - errno = 22

All I can get from google is to replace a kernel header.  I've done that
(I'm using kernel 2.4.19, all kernel headers are 2.4.19, etc.) with no
change in behaviour.

I am using nearly identical kernels on both host and UML.  I do have
/dev/net/tun (and added /dev/net/tap, just to see) with the proper
major/minor numbers (10/200).

I am at a loss.  Any pointers, suggestions, or URLs would be appreciated.
Thanks.
