330  * IMPORTANT REMARKS:
331  * 1. the cmng_init struct does not represent the contiguous internal ram
332  *    structure. the driver should use the XSTORM_CMNG_PERPORT_VARS_OFFSET
333  *    offset in order to write the port sub struct and the
334  *    PFID_FROM_PORT_AND_VNIC offset for writing the vnic sub struct (in other
335  *    words - don't use memcpy!).
336  * 2. although the cmng_init struct is filled for the maximal vnic number
337  *    possible, the driver should only write the valid vnics into the internal
338  *    ram according to the appropriate port mode.
