[PATCH] SIT tunnels over IPsec

[-- Attachment #1: Type: text/plain, Size: 415 bytes --]

Hi!

The attached patch fixes IPv6-in-IPv4 (SIT) tunnel over IPsec. Without 
it the SIT packets originated from the same host as the IPsec endpoint 
is leave the interface unencrypted and of course the tunnel doesn't 
work. The patch fixes it. Tested.

Please apply.

Thanks,

Michal Ludvig
