/*
 * congestion management port init api description
 * 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.
