Subject: [MOBILE-IP] Routing socket message bitmask for reverse tunnel support

We are thinking about implementing two new bitmask flags
for routing socket message identifying the source address
and incoming interface of the packet to support reverese
tunnel and overlapping private addresses visiting same
FA on different links ( i.e. by sending routing socket message
from mipagent to kernel, we will ask the kernel to do the
source addr based routing lookup for reverse tunnel).

The proposal for adding two bitmasks for this purpose in the
route.h header file is:

#define RTA_SRC         0x100   /* Source sockaddr present */
#define RTA_SRCIFP      0x200   /* Source interface name sockaddr present */

I would like to know if there are any routing socket implementors
who have used similar name space for these bitflags for mobileip
implementation.

Thanks,
