		 * Second IF condition:
		 * The below condition happens when an MSDU is spread
		 * across multiple buffers. This can happen in two cases
		 * 1. The nbuf size is smaller then the received msdu.
		 *    ex: we have set the nbuf size to 2048 during
		 *        nbuf_alloc. but we received an msdu which is
		 *        2304 bytes in size then this msdu is spread
		 *        across 2 nbufs.
		 *
		 * 2. AMSDUs when RAW mode is enabled.
		 *    ex: 1st MSDU is in 1st nbuf and 2nd MSDU is spread
		 *        across 1st nbuf and 2nd nbuf and last MSDU is
		 *        spread across 2nd nbuf and 3rd nbuf.
		 *
		 * for these scenarios let us create a skb frag_list and
		 * append these buffers till the last MSDU of the AMSDU
		 * Third condition:
		 * This is the most likely case, we receive 802.3 pkts
		 * decapsulated by HW, here we need to set the pkt length.
