Bug Description
A new option present in Kernel 3.0 enables exporting all wifi packets on the iwlwifi driver through (generic) netlink, for debug purposes (an intel undisclosed svtool). This should not be enabled by default, as it forces all wifi packet to be delivered through netlink (causing a large amount of netlink operations, leading to cpu overhead, and battery overhead).
The offending option is:
CONFIG_
This should be disabled in production systems, as it only matters for development/

Hi Alfredo,
I've posted a test kernel with CONFIG_ IWLWIFI_ DEVICE_ SVTOOL disabled (ie =n) at the following location. Please test and let me know your results. Thanks.
