Summary:                    Bridge-utils broken under kernel 2.4
Description: 
Snapshot buildroot-20080905

The bridge-utils package compiles but the brctl command fails.
The error message is:
# brctl addbr br0
add bridge failed: Invalid argument

I think this is a problem with the bridge-utils 1.4. The former version
1.06 works fine.

My configuration is: 386, kernel 2.4, busybox 1.11.x
The project is openMGB, a RDC based NAS with WAP.

I don't have access to any system with a 2.4 kernel anymore - Does it work
if you change the version in bridge.mk back to v1.06? If so, please report
the problem with bridge-utils upstream.

1.4 seems to use /sys/class/net which wouldn't exist on linux 2.4

The README claims to only use sysfs stuff on 2.6 kernels, but I don't see
any fallback code. Probably the README is just stale - The bridge-utils
upsteam tarball seems pretty broken in general (no configure, configure.in
using wrong version, stale README, ..)

I don't have a problem with reverting to 1.06 if that fixes the bug
reporter's issue.

Do we need to support 2.4? I don't think you can build it using buildroot?
I would've expected a project that is using current buildroot and current
busybox to also run a current kernel..

I don't personally have any interest in 2.4, but if we can keep it working
with small effort, then that's fine with me.
