freebsd-dev/sys/contrib/octeon-sdk/cvmx-helper-board.c
Juli Mallett 15fe2454ae o) Expand the CIU driver to be aware of newly-allocated parts of the IRQ range. 
o) Add 'octm', a trivial driver for the 10/100 management ports found on some
   Octeon systems.
o) Make the Simple Executive's management port helper routines compile on
   FreeBSD (namely by not doing math on void pointers.)
o) Add a cvmx_mgmt_port_sendm routine to the Simple Executive to send an mbuf
   so there is only one copy in the transmit path, rather than having to first
   copy the mbuf to an intermediate buffer and then copy that to the Simple
   Executive's transmit ring.
o) Properly work out MII addresses of management ports on the Lanner MR-730.
   XXX The MR-730 also needs some patches to the MII read/write routines, but
       this is sufficient for now.  Media detection will be fixed in the future
       when I can spend more time reading the vendor-supplied patches.
