ip_forward() function

[Matthew Closson <matt_(_at_)_scrapshells_(_dot_)_com>]

Where is the code for the ip_forward() function in 3.8?

I found the prototype in: /usr/src/sys/netinet/ip_var.h

void	ip_forward(struct *mbuf, int);

but no function definition.

I also did a grep -sR "ip_forward" /usr/src
and all I found was the function being called several times
from /usr/src/sys/netinet/ip_input.c, but no actual code showing
how the function works.  I'm probably looking for this in the
wrong way, any ideas?  Thanks,
