+Subject: [PATCH 1/2] wl12xx: Decrease number of RX transactions
+
+On weak platforms, it is crucial to keep the number of SDIO transactions
+to a bare minimum. It is probably more important to keep CPU utilization
+low, than to handle FW events asap.
+
+In order to decrease the number of RX transactions, set the FW to only
+wake up the host when it has at least 4 pending packets. In addition,
+increase the relevant timeout, so the FW could actually reach this
+threshold.
