+Subject: [PATCH] brcmfmac: keep ARP and ND offload enabled during WOWL
+
+Currently ARP and ND (IPv6 Neigbor Discovery) offload get disabled
+on entering suspend. However when firmwares support the wowl_cap
+iovar then these offload routines can be kept enabled as they
+will work during WOWL as well.
