From 77ddaa108f727b5ef3be004b952d2c3d3ffc48e5 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Sun, 15 May 2011 11:10:29 +0300 Subject: wl12xx: add automatic rx streaming triggers When rx_streaming.interval is non-zero, use automatic rx streaming. Enable rx streaming on the each rx/tx packet, and disable it rx_streaming.duration msecs later. When rx_streaming.always=0 (default), rx streaming is enabled only when there is a coex operation.
