From fb10167478a3a8e29fe122a7bf4c67b5cfc48a1b Mon Sep 17 00:00:00 2001 From: Inaky Perez-Gonzalez Date: Thu, 7 May 2009 10:27:42 -0700 Subject: [PATCH] wimax/i2400m: introduce module parameter to disable entering power save The i2400m driver waits for the device to report being ready for entering power save before asking it to do so. This module parameter allows control of said operation; if disabled, the driver won't ask the device to enter power save mode. This is useful in setups where power saving is not so important or when the overhead imposed by network reentry after power save is not acceptable; by combining this with parameter 'idle_mode_disabled', the driver will always maintain both the connection and the device in active state.
