35bb4dee50 osi: eqos: only interface APIs accessible form OSD 
Issue:	Many non API functions are accessible from
	OSD code which can be used to update/access
	HW registers.
Fix:	Move non API function to local files and
	remove header files from code shared with OSD
	so these function can be accessible only
	within OSI code

d39e02d47e osi: don't expose DMA ops to OSD 
Issue: Currently OSD has access to osi_dma_ops
so these operations can be changed by OSD.
Also each entry funnction has checks for validating
these function pointers which would increase the
unit tests as well.

Fix: Move dma_ops to inside OSI and set a flag
indicate that DMA software init done. Each entry
function needs to check only flag.

It also fixes couple of doxygen comments issues.

3f204d6f16 nvthernetrm: Add IVC support for OSI 
In case of virtualization the OSI functions will be handled
at Ethernet Server. Add IVC support where OSD can send
IVC packets to ethernet server. Ethernet Server parses the
messages and calls the corresponding OSI API.

OSI and few DMA API's are updated to support osi_core as an
argument.

Issue:  DMA will be in suspend state if there is no buffer allocation
        happen to HW. If DMA is in suspend state, no interrupt will
        occur for channel which leads to not calling of
        osd_receive_packet().

Fix:    Whenever there is rx buffer kernel memory allocation failure, desc
        will be updated with reserve rx buffer. This reserved buffer is
	already allocated at the time of ether_open. Aim of same to
	make sure rx DMA always have buffer and not go in suspend state.
