Good afternoon list,
I have a single board computer with 2 cpu each running their own netbsd
kernel:

PHY--CPU1-----------logic---------CPU2---PHY
            mii bus         mii bus

after I'm done processing a packet on CPU1 how can I address it
to CPU2? Is there a kernel level interface to the MII bus I could
use for this (i.e read/write)? Or any other idea, like shared memory,
anything that you think could work? Is there an interprocessor 
communication API that I could use for this?

By the way, no SMP support for these CPU.


Thanks a lot.
Jerry
