* the api works as follows:
* the driver should pass the cmng_init_input struct, the port_init function
* will prepare the required internal ram structure which will be passed back
* to the driver (cmng_init) that will write it into the internal ram.
*
* IMPORTANT REMARKS:
* 1. the cmng_init struct does not represent the contiguous internal ram
* structure. the driver should use the XSTORM_CMNG_PERPORT_VARS_OFFSET
* offset in order to write the port sub struct and the
* PFID_FROM_PORT_AND_VNIC offset for writing the vnic sub struct (in other
* words - don't use memcpy!).
* 2. although the cmng_init struct is filled for the maximal vnic number
* possible, the driver should only write the valid vnics into the internal
* ram according to the appropriate port mode.
