I want to create a new chain of mbufs, I am using the function
m_devget, my question is, what if I have data larger than 1500 bytes,
say 3000 bytes, can I pass the buffer into m_devget and m_devget will
chain, link out the data correctly or do I have to break up the large
data myself, into 1500 bytes chunks and call m_devget twice?
This is the kind of question you should be able to answer for yourself,
with a quick look at the kernel code. A handy tool for this purpose is
'cscope', and there is a "makefile" hook to make the cscope database
("make cscope").
To get you started, m_devget() is in xnu/bsd/kern.
If this is not the proper forum for asking this question I would
appreciate some feedback on where I should be asking these questions.
This is the right forum.

Justin
