Public bug reported:
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_IWLWIFI_DEVICE_SVTOOL=y
This should be disabled in production systems, as it only matters for
development/testing.
