This is based on (but now quite far from) the
original work from Luis and Eliad. Add support
for configuring WoWLAN triggers, and getting
the configuration out again. Changes from the
original patchset are too numerous to list,
but one important change needs highlighting:
the suspend() callback is passed NULL for the
trigger configuration if userspace has not
configured WoWLAN at all.Signed-off-by: Luis R. Rodriguez

The index cannot be used to reliably reconstruct a phy
name, so explicitly add the phy name to sysfs so that scripts
can figure out the parent phy device for a particular
wireless interface.Signed-off-by: Ben Greear

If a device has multiple MAC addresses, userspace will
need to know about that. Similarly, if it allows the
MAC addresses to vary by a bitmask.If a driver exports multiple addresses, it is assumed
that it will be able to deal with that many different
addresses, which need not necessarily match the ones
programmed into the device; if a mask is set then the
device should deal addresses within that mask based
on an arbitrary "base address".To test it all and show how it is used, add support
to hwsim even though it can't actually deal with
addresses different from the default.Signed-off-by: Johannes Berg

Scanned BSS entries are timestamped with jiffies, which doesn't
increment across suspend and hibernate. On resume, every BSS in the
scan list looks like it was scanned within the last 10 seconds,
irregardless of how long the machine was actually asleep. Age scan
results on resume with the time spent during sleep so userspace has a
clue how old they really are.Signed-off-by: Dan Williams

This should help implement suspend/resume in mac80211, these
hooks will be run before the device is suspended and after it
resumes. Therefore, they can touch the hardware as much as
they want to.Signed-off-by: Johannes Berg

Remove converting the MAC address to a string by a direct byte
conversion and use %pM instead, since the code is now boilerplate
use a macro to define the show functions, and also use the shorter
__ATTR_RO macro to define the attributes.Signed-off-by: Johannes Berg

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.Signed-off-by: Kay Sievers

This patch creates the core cfg80211 code along with some sysfs bits.
This is a stripped down version to allow mac80211 to function, but
doesn't include any configuration yet except for creating and removing
virtual interfaces.This patch includes the nl80211 header file but it only contains the
interface types which the cfg80211 interface for creating virtual
interfaces relies on.Signed-off-by: Johannes Berg
