From: Wey-Yi Guy <wey-yi.w....@intel.com> commit f35291082294ca6737953bbe4e9491ede04ab822 upstream.
5000 series has issue supporting power save idle mode: commit 9dc2153315650eae220898668b6aa56a25c130be iwlwifi: always support idle mode for agn devices For agn devices, always support idle mode which help power consumption in idle unassociated state. the above changes cause 5000 become not stable when power management is "on" http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2312 Cc: sta...@kernel.org #2.6.39, #3.0.0 Reported-by: Devin J.
