 284  * the api works as follows:
 285  * the driver should pass the cmng_init_input struct, the port_init function
 286  * will prepare the required internal ram structure which will be passed back
 287  * to the driver (cmng_init) that will write it into the internal ram.
 288  *
 289  * IMPORTANT REMARKS:
 290  * 1. the cmng_init struct does not represent the contiguous internal ram
 291  *    structure. the driver should use the XSTORM_CMNG_PERPORT_VARS_OFFSET
 292  *    offset in order to write the port sub struct and the
 293  *    PFID_FROM_PORT_AND_VNIC offset for writing the vnic sub struct (in other
 294  *    words - don't use memcpy!).
 295  * 2. although the cmng_init struct is filled for the maximal vnic number
 296  *    possible, the driver should only write the valid vnics into the internal
 297  *    ram according to the appropriate port mode.
