Since P2P device doesn't have a netdev associated to it,
we cannot prevent the user to start it when in RFKILL.
So refuse to even add it when in RFKILL.

My locking rework/race fixes caused a regression in the
registration, causing uevent notifications for wireless
devices before the device is really fully registered and
available in nl80211.

Fix this by moving the device_add() under rtnl and move
the rfkill to afterwards (it can't be under rtnl.)

When a P2P GO interface goes down, cfg80211 doesn't properly
tear it down, leading to warnings later. Add the GO interface
type to the enumeration to tear it down like AP interfaces.
Otherwise, we leave it pending and mac80211's state can get
very confused, leading to warnings later.

In most cases, host that receives IPv4 and IPv6 multicast/broadcast
packets does not do anything with these packets. Therefore the
reception of these unwanted packets causes unnecessary processing
and power consumption.

Packet coalesce feature helps to reduce number of received
interrupts to host by buffering these packets in firmware/hardware
for some predefined time. Received interrupt will be generated when
one of the following events occur.
a) Expiration of hardware timer whose expiration time is set to
maximum coalescing delay of matching coalesce rule.
b) Coalescing buffer in hardware reaches it's limit.
c) Packet doesn't match any of the configured coalesce rules.

This patch adds set/get configuration support for packet coalesce.
User needs to configure following parameters for creating a coalesce
rule.
a) Maximum coalescing delay
b) List of packet patterns which needs to be matched
c) Condition for coalescence. pattern 'match' or 'no match'
Multiple such rules can be created.

This feature needs to be advertised during driver initialization.
Drivers are supposed to do required firmware/hardware settings based
on user configuration.

If it *is* still set when the netdev is being deleted,
then we are about to leak a pointer.  Warn and clean up
in that case.

The change to use atomic_inc_return() for assigning the wiphy
index made the first wiphy index 1 instead of 0. This is fine,
but we all habitually type "phy0" when we're testing, so make
it go back to 0 instead of 1 by subtracting 1 from the index.
