Hello Karthik,
The problem is that these symbols are not exported by the kernel or IPv6
module, depending
on how you configured IPv6, and hence, they couldn't be resolved when you
run either insmod
or depmod of mip6.
If you have built IPv6 as part of the proper kernel, you could simply edit
'kernel/ksyms.c'
file with the exported unresolved symbols. Also, you need to place a
header file in
include/linux directory.
I haven't created any patch against the kernel for the MIP6 patch yet but
until then, you
could use make the changes as shown below.
Thanks,
Venkat

Please respond to
usagi-users
Sorry, my oversight. Found it under usagi/kernel/usagi/net/
Seems to work fine now (except for the mobile_ip6 module, which
reports a number of unresolved symbols, but that's for a different
day's troubleshooting :)
thanks!
