27 /* tunnel.c: an IP tunnel driver
29 The purpose of this driver is to provide an IP tunnel through
30 which you can tunnel network traffic transparently across subnets.
41 Made the tunnels use dev->name not tunnel: when error reporting.
47 Changed to tunnel to destination gateway in addition to the
48 tunnel's pointopoint address
56 /* Things I wish I had known when writing the tunnel driver:
60 contains the tunnel device that _we_ are.
