wl12xx: schedule recovery on command timeout (f482b762) · Commits · 戴 / test

We use a long timeout (2 seconds) when sending commands to the FW. When a command times out, it means the FW is stuck, and we should commence recovery. This should make recovery times shorter as we'll recover on the first timeout indication. Signed-off-by:
