450  * wlan_defrag_elem_fragseq() - Defragment sequence of element fragments
451  *
452  * @inline_defrag: Whether to use inline defragmentation, wherein the
453  * defragmentation is carried out inline within the source buffer and no
454  * memmoves/memcopy would be required for the lead element.
455  * @fragbuff: Source buffer containing the element fragment sequence starting
456  * with the Element ID of the lead element. The buffer should not contain any
457  * material other than elements. If inline defragmentation is enabled, the
458  * corresponding defragmented payload will be generated inline into this buffer
459  * and the defragmented payload will start after the location of the lead
460  * element's element ID, element length, and (if the lead element's element ID
461  * is WLAN_ELEMID_EXTN_ELEM), the element ID extension. This defragmented
462  * payload will not contain the headers of any of the other fragments in the
463  * fragment sequence.
464  * @fragbuff_maxsize: Maximum size of fragbuff. This should be greater than or
465  * equal to the total size of the element fragment sequence, inclusive of the
466  * header and payload of the leading element and the headers and payloads of all
467  * subsequent fragments applicable to that element.
468  * @defragbuff: The destination buffer into which the defragmented payload
469  * should be copied. This is inapplicable and ignored if inline_defrag is true.
470  * The defragmented payload will be copied to the start of the destination
471  * buffer without including the headers of the lead element and the subsequent
472  * fragment elements, and (if the lead element's element ID is
473  * WLAN_ELEMID_EXTN_ELEM), without including the element ID extension.
474  * @defragbuff_maxsize: Maximum size of defragbuff. This is inapplicable and
475  * ignored if inline_defrag is true. The size should be large enough to contain
476  * the entire defragmented payload, otherwise an error will be returned.
477  * @defragpayload_len: Pointer to the location where the length of the
478  * defragmented payload should be updated. Irrespective of whether inline_defrag
479  * is true or false, this will not include the sizes of the headers of the lead
480  * element and subsequent fragments, and (if the lead element's element ID is
481  * WLAN_ELEMID_EXTN_ELEM), it will not include the size of the lead element's
482  * element ID extension. Please note standards related limitation given in
483  * function description below.
484  *
485  * Defragment a sequence of element fragments. If the source buffer does not
486  * contain an element fragment sequence (in the beginning), an error is
487  * returned. An inline mode is available to carry out the defragmentation within
488  * the source buffer in order to reduce buffer requirements and to eliminate
489  * memory copies/moves for the lead element. In the inline mode, the buffer
490  * content (if any) after the fragments is moved as well. The contents of the
491  * defragmented payload are intended for end consumption by control path
492  * protocol processing code within the driver in a manner uniform with other
493  * protocol data in byte buffers, and not for onward forwarding to other
494  * subsystems or for intrusive specialized processing different from other
495  * protocol data. Hence zero copy methods such as network buffer fragment
496  * processing, etc. are not used in this use case.  Additionally, this API is
497  * intended for use cases where the nature of the payload is complex and it is
498  * infeasible for the caller to skip the (un-defragmented) fragment boundaries
499  * on its own in a scalable and maintainable manner. Separately, please note a
500  * limitation arising from the standard wherein if the caller passes a truncated
501  * maximum buffer size such that the buffer ends prematurely just at the end of
502  * a fragment element with length 255, the function will have to conclude that
503  * the last successfully parsed fragment element is the final one in the
504  * fragment sequence, and return results accordingly. If another fragment
505  * actually exists beyond the given buffer, this function cannot detect the
506  * condition since there is no provision in the standard to indicate a total
507  * fragment sequence size in one place in the beginning or anywhere else. Hence
508  * the caller should take care to provide the complete buffer with the max size
509  * set accordingly.
