283/* congestion management port init api description
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.
