Grr, I've almost lost this... In article <3EF37458.3070103@us.ibm.com> (at Fri, 20 Jun 2003 13:53:44 -0700), Krishna Kumar <krkumar@us.ibm.com> says: > 1.

Rename inet6_dump_fib() to __inet6_dump_fib() and introduce extra argument. and call it like inet6_dump_fib() { __inet6_dump_fib(...,0); } and inet6_dump_prefix() { __inet6_dump_fib(...,1); } etc. > 3.
