#23 IPv6 forwarding activation before module loading

[Anonymous]

When using <forwarding type="ipv6" /> (or <forwarding
type="ip" />) it could happen that IPv6 modules aren't
loaded in the moment when the umlboot script performs
the 'echo 1 >' command.

It would be desirable to check the module loading
before execute the 'echo 1>' command. However, blindly
execute a modprobe before could fail if IPv6
functionallity is not provided as kernel module (it
could be included in the kernel itself).

Maybe a solution could be perform the 'echo 1>' command
and, it fails, perform the modprobe and then retry the
'echo 1>' command.
