+ *
+ * msdu_limit_error
+ *		Indicates that the MSDU threshold was exceeded and thus all the

+ *		Opaque service code between PPE and Wi-Fi
+ *
+ * priority_valid
+ *		This field gets passed on by REO to PPE in the EDMA descriptor
+ *
+ * intra_bss
+ *		This packet needs intra-BSS routing by SW as the 'vdev_id'
+ *		for the destination is the same as 'vdev_id' (from 'RX_MPDU_PCU_START')
+ *		that this MSDU was got in.
+ *
+ * dest_chip_id
+ *		If intra_bss is set, copied by RXOLE from 'ADDR_SEARCH_ENTRY'

+ *		queueued
+ *
+ * multicast_echo
+ *		If set, this packet is a multicast echo, i.e. the DA is
+ *		multicast and Rx OLE SA search with mcast_echo_check = 1
+ *		passed. RXDMA should release such packets to WBM.

+ *
+ * msdu_length
+ *		MSDU length in bytes after decapsulation.
+ *		This field is still valid for MPDU frames without A-MSDU.
+ *		It still represents MSDU length after decapsulation

+ *
+ * ipsec_esp
+ *		Set if IPv4/v6 packet is using IPsec ESP.
+ *
+ * l3_offset
+ *		Depending upon mode bit, this field either indicates the
+ *		L3 offset in bytes from the start of the RX_HEADER or the IP
+ *		offset in bytes from the start of the packet after
+ *		decapsulation. The latter is only valid if ipv4_proto or
