* gtp_nl.h now contains exported netlink attributes and commands to
userspace.
* gtp.h contains internal definition for the GTP protocol implementation.
This patch detaches the hashtable and the UDP setup from the
GTP_CMD_TUNNEL_* command. The gtp kernel modules needs to support
UDP socket reconfiguration.
After this patch, the steps to bring up a tunnel are:
1st) bring up the device gtp0 via rtnetlink using the "gtp" link type.
2nd) attach a configuration to the gtp0 device, it includes the
initialization of the hashes and the UDP socket, via genetlink
"gtp" family using the GTP_CMD_CFG_NEW command.
3rd) add/delete tunnels using genetlink "gtp" family and GTP_CMD_TUNNEL_*
commands.
Still unusable, but the netlink interface looks in better shape.
