Hello,
The brctl applet doesn't compile with kernels < 2.6.7 because the
ioctls were renamed in that version.
I need to work with an ancient kernel (2.4.18) because of some
vendor-supplied binary-only kernel module that only works in that
version.
Thanks again for making such a great tool!
So here is the patch against busybox-1.13.2:
