[PATCH 3/5] iwlwifi: 5150 compute ct kill threshold

[Reinette Chatre]

From: Tomas Winkler <tomas.winkler@intel.com>

This patch adds computation of ct kill threshold
for 5150. Threshold is computed from calibration
data in the EEPROM.

Awesome, is the 5150 firmware available in the usual places now?  I
don't see it at:

http://intellinuxwireless.org/?n=Downloads

and unless I'm completely blind:

+#define IWL5150_MODULE_FIRMWARE "iwlwifi-5150" IWL5150_UCODE_API ".ucode"

new ucode is required :)

yes - new ucode is required but is not yet available for release. When
the ucode is released (we will announce it) it will be available in the
spot you mention above.
