[VLAN]: Reduce memory consumed by vlan_groups
Currently each vlan_groupd contains 8 pointers on arrays with 512
pointers on struct net_device each :) Such a construction "in many
cases ... wastes memory".
My proposal is to allow for some of these arrays pointers be NULL,
meaning that there are no devices in it. When a new device is added
to the vlan_group, the appropriate array is allocated.
The check in vlan_group_get_device's is safe, since the pointer
vg->vlan_devices_arrays[x] can only switch from NULL to not-NULL.
The vlan_group_prealloc_vid() is guarded with rtnl lock and is
also safe.
I've checked (I hope that) all the places, that use these arrays
and found, that the register_vlan_dev is the only place, that can
put a vlan device on an empty vlan_group.
Rough calculations shows, that after the patch a setup with a
single vlan dev (or up to 512 vlans with sequential vids) will
occupy approximately 8 times less memory.
The question I have is - does this patch makes sense, or a totally
new structures are required to store the vlan_devs?

This is useful for drivers who need to provide tkip key to their
HW to enable HW encryption.

This patch adds translation for the RX status of an incoming packet.
The incoming status has to be translated to the old scheme in order to know
if the decryption has been done, MIC failure has occured, TTAK is valid etc...
This translation is mandatory for all RX packets when using 5300 and for
all HT packets using 4965.

This patch cleans up the set_key flow. Rxon with hw encryption bit set is
not sent upon each call to set_key. Separation is made between global key
(WEP) and dynamic key (TKIP + CCMP and WEP in some cases).
