	 *     RSN IE length as extra 2 bytes but dont fill the IE data with
	 *     capabilities, resulting in failure in unpack core due to length
	 *     mismatch. Check sir_validate_and_rectify_ies for more info.

	 * 2.  In the API wma_process_rmf_frame(), the driver trims the CCMP
	 *     header by overwriting the IEEE header to memory occupied by CCMP
	 *     header, but an overflow is possible if the memory allocated to
	 *     frame is less than the sizeof(struct ieee80211_frame) +CCMP
	 *     HEADER len, so allocating 100 bytes would solve this issue too.
	 *
	 * 3.  CCMP header is pointing to orig_hdr +
	 *     sizeof(struct ieee80211_frame) which could also result in OOB
	 *     access, if the data len is less than
	 *     sizeof(struct ieee80211_frame), allocating extra bytes would
	 *     result in solving this issue too.
