Hi,
I am new to FreeBSD kernel programming.
Currently I am trying to work on mbuf data manupulation.

Now, I need to retrive all data in mbuf chain ( mbufs linked by
m_next). I am working ip_output() in netinet/ip_output.c
Does there exist inbuilt function/macro to retrive all the data in mbuf chain?
man 9 mbuf; look for m_copydata.
