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.
