rt2x00dev->default_ant should be initialized once by the driver,
and should not be changed afterwards. Because rt2x00lib_config_antenna()
was using a reference to the struct antenna_setup it actually had the oppurtunity
to change the default antenna setting and it actually did that during the validation.
Instead of passing a pointer to antenna_setup the entire structure should be copied.

This finally opens up the ability to put mac80211 devices
into different network namespaces. As long as you don't
have sysfs, that is.

Signed-off-by: John W. Linville <linville@tuxdriver.com>
In order to make cfg80211/nl80211 aware of network namespaces,
we have to do the following things:
* del_virtual_intf method takes an interface index rather
than a netdev pointer - simply change this
* nl80211 uses init_net a lot, it changes to use the sender's
network namespace
* scan requests use the interface index, hold a netdev pointer
and reference instead
* we want a wiphy and its associated virtual interfaces to be
in one netns together, so
- we need to be able to change ns for a given interface, so
export dev_change_net_namespace()
- for each virtual interface set the NETIF_F_NETNS_LOCAL
flag, and clear that flag only when the wiphy changes ns,
to disallow breaking this invariant
* when a network namespace goes away, we need to reparent the
wiphy to init_net
* cfg80211 users that support creating virtual interfaces must
create them in the wiphy's namespace, currently this affects
only mac80211
The end result is that you can now switch an entire wiphy into
a different network namespace with the new command
iw phy#<idx> set netns <pid>
and all virtual interfaces will follow (or the operation fails).

There are still two places in mac80211 that hardcode
the initial net namespace (init_net). One of them is
mandated by cfg80211 and will be removed by a separate
patch, the other one is used for finding the network
device of a pending packet via its ifindex.
Remove the latter use by keeping track of the device
pointer itself, via the vif pointer, and avoid it
going stale by dropping pending frames for a given
interface when the interface is removed.
To keep track of the vif pointer for the correct
interface, change the info->control.vif pointer's
internal use to always be the correct vif, and only
move it to the vif the driver expects (or NULL for
monitor interfaces and injected packets) right before
giving the packet to the driver.

This update cleans up the receive address register initialization. The
main purpose of this is to clean out some redundancy that was introduced
due to having multiple ways of setting the receive address registers.
Instead of having a specialized function to set one register and one to set
all of them it makes more sense to just go through the list calling the
function that is needed to set the individual registers.
