Jouni reported that certain combinations of hwsim test cases failed,
and we found that beaconing was erroneously enabled too early on any
channel switch, which lead to the BI of 2000 TU from the first test
case to leak into the second one, which then didn't beacon properly.

To fix this, set data->beacon_int to zero when all stop beaconing so
that beaconing cannot be started (which was intended as 'restarted')
elsewhere.

Additionally, Jouni found that due to this 'restart' and the beacon
interval handling station interfaces would also have a needlessly
running beacon timer all the time, of course not doing anything.

To also fix the latter case only use the beacon interval when it's
actually needed, i.e. when beaconing gets enabled.

This modifies cfg80211_vendor_event_alloc() with an additional argument
struct wireless_dev *wdev. __cfg80211_alloc_event_skb() is modified to
take in *wdev argument, if wdev != NULL, both the NL80211_ATTR_IFINDEX

These changes make it easier for drivers to add ifindex indication in

802.11ad adds new a network type (PBSS) and changes the capability
field interpretation for the DMG (60G) band.
The same 2 bits that were interpreted as "ESS" and "IBSS" before are
re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid
values are: "IBSS", "PBSS" (new) and "AP".

In order to get the BSS struct for the new PBSS networks, change the
cfg80211_get_bss() function to take a new enum ieee80211_bss_type
argument with the valid network types, as "capa_mask" and "capa_val"
no longer work correctly (the search must be band-aware now.)

The remaining bits in "capa_mask" and "capa_val" are used only for
privacy matching so replace those two with a privacy enum as well.

When a fully converted cfg80211 driver needs cfg80211-wext for
userspace API purposes, the symbols need not be exported. When
other drivers (orinoco/hermes or ipw2200) are enabled, they do
need the symbols exported as they use them directly.

Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig
symbol (instead of just CFG80211_WEXT) and export the functions
only if requested - this saves about 1/2k due to the size of
EXPORT_SYMBOL() itself.

The WRB header is setup by wrb_fill_hdr() routine. This routine currently
gets some of the WRB params as args and figures out rest of the WRB params
by looking at various fields in skb (like gso, checksum, vlan-tag etc).
All these params could instead be retrieved from the skb into a structure
and passed to this routine. This separates wrb_fill_hdr() to only provide
chip-specific code to fill the WRB. This also makes it simple to support
chips with different WRB formats.

NAND-tree is used to check wiring between MAC and PHY using NAND gates
on the PHY side, hence the name.

NAND-tree initial status is latched at reset by probing the IRQ pin.
However some devices are sharing the PHY IRQ pin with other peripherals
such as Atmel SAMA5D[34]x-EK boards when using the optional TM7000
display module, therefore they are switching the PHY in NAND-tree test
mode depending on the current IRQ line status at reset.

This patch ensure PHY is not in NAND-tree test mode for all Micrel PHYs
using IRQ line as a NAND-tree toggle mode at reset.

There is a capability which let the hw could change the settings
automatically when the power change to ON. However, the USB reset
would reset the settings to the hw default, so the driver has to
restore the relative settings. Otherwise, it would influence the
functions of the hw, and the compatibility for the USB hub and
USB host controller.

The relative settings are as following.
 - set the power down scale to 96.
 - enable the power saving function of USB 2.0.
 - disable the ALDPS of ECM mode.
 - set burst mode depending on the burst size.
 - enable the flow control of endpoint full.
 - set fifo empty boundary to 32448 bytes.
 - enable the function of exiting LPM when Rx OK occurs.
 - set the connect timer to 1.

If skb allocation fails once the IP header has been received, the rx state is
being set to WAIT_SYNC. The logic, though, shouldn't directly return, as the
buffer may contain a full packet, and therefore the WAIT_SYNC state needs to be
processed (resetting state to WAIT_IP, clearing rx_buf_size and re-initializing
rx_buf_missing).

So, just let the while loop continue so that in the next iteration the WAIT_SYNC
state cleanly stops the loop. The WAIT_SYNC processing will be done just after
that, only if the end of packet is flagged.

Driver keeps adding multicast addresses without deleting removed MACs and
worrying about adapters filter limit. This results into actual count of programmed
multicast addresses get accumulated over the time and overruns the adapter's
filter limit without putting device in ACCEPT_ALL_MULTI mode. This causes
newly added multicast traffic to fail after the sequence of addition - deletion
in certain pattern.

This issue is seen only when netdev's mcast list count is less than adapters
mcast filter limit.

e.g. If adapters multicast filter limit is 38 per function
     then following sequence would result in multicast traffic failure for
     newly added MACs.
     - add less than 38 multicast MACs
     - remove previously added multicast MACs
     - add new multicast MACs (less than 38)
