The network device operation for reading statistics is only called
in one place, and it ignores the return value. Having a structure
return value is potentially confusing because some future driver could
incorrectly assume that the return value was used.
Fix all drivers with ndo_get_stats64 to have a void function.

In ieee80211_xmit_fast(), 'info' is initialized to point to the skb
that's passed in, but that skb may later be replaced by a clone (if
it was shared), leading to an invalid pointer.
This can lead to use-after-free and also later crashes since the
real SKB's info->hw_queue doesn't get initialized properly.
Fix this by assigning info only later, when it's needed, after the
skb replacement (may have) happened.

Add the ability for an AP (and associated VLANs) to perform
multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames
(possibly within 802.1Q). If enabled, such frames are to be sent
to each station separately, with the DA replaced by their own
MAC address rather than the group address.
Note that this may break certain expectations of the receiver,
such as the ability to drop unicast IP packets received within
multicast L2 frames, or the ability to not send ICMP destination
unreachable messages for packets received in L2 multicast (which
is required, but the receiver can't tell the difference if this
new option is enabled.)
This also doesn't implement the 802.11 DMS (directed multicast
service).

Since drivers know nothing about AP_VLAN interfaces, trying to
call drv_set_default_unicast_key() just results in a warning
and no call to the driver. Avoid the warning by not calling the
driver for this on AP_VLAN interfaces.
This means that drivers that somehow need this call for AP mode
will fail to work properly in the presence of VLAN interfaces,
but the current drivers don't seem to use it, and mac80211 will
select and indicate the key - so drivers should be OK now.

When mac80211 abandons an association attempt, it may free
all the data structures, but inform cfg80211 and userspace
about it only by sending the deauth frame it received, in
which case cfg80211 has no link to the BSS struct that was
used and will not cfg80211_unhold_bss() it.
Fix this by providing a way to inform cfg80211 of this with
the BSS entry passed, so that it can clean up properly, and
use this ability in the appropriate places in mac80211.
This isn't ideal: some code is more or less duplicated and
tracing is missing. However, it's a fairly small change and
it's thus easier to backport - cleanups can come later.

All conflicts were simple overlapping changes except perhaps
for the Thunder driver.
That driver has a change_mtu method explicitly for sending
a message to the hardware. If that fails it returns an
error.
Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.
However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

Merge tag 'mac80211-next-for-davem-2016-10-28' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
Among various cleanups and improvements, we have the following:
* client FILS authentication support in mac80211 (Jouni)
* AP/VLAN multicast improvements (Michael Braun)
* config/advertising support for differing beacon intervals on
multiple virtual interfaces (Purushottam Kushwaha, myself)
* deprecate the old WDS mode for cfg80211-based drivers, the
mode is hardly usable since it doesn't support any "modern"
features like WPA encryption (2003), HT (2009) or VHT (2014),
I'm not even sure WEP (introduced in 1997) could be done.

gcc -Wmaybe-uninitialized reports a bug in aes_siv_encryp:
net/mac80211/fils_aead.c: In function ‘aes_siv_encrypt.constprop’:
net/mac80211/fils_aead.c:84:26: error: ‘tfm2’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
At the time that the memory allocation fails, 'tfm2' has not been
allocated, so we should not attempt to free it later, and we can
simply return an error.

With the previous commits, initial FILS authentication/association
support is now functional in mac80211-based drivers for station role
(and FILS AP case is covered by user space in hostapd withotu requiring
mac80211 changes).

This adds support for encrypting (Re)Association Request frame and
decryption (Re)Association Response frame when using FILS in station
mode.

The special SAE case should be limited only for SAE since the more
generic AUTH_DATA can now be used with other authentication algorithms
as well.

This adds defines and nl80211 extensions to allow FILS Authentication to
be implemented similarly to SAE. FILS does not need the special rules
for the Authentication transaction number and Status code fields, but it
does need to add non-IE fields. The previously used
NL80211_ATTR_SAE_DATA can be reused for this to avoid having to
duplicate that implementation. Rename that attribute to more generic
NL80211_ATTR_AUTH_DATA (with backwards compatibility define for
NL80211_SAE_DATA).
Also document the special rules related to the Authentication
transaction number and Status code fiels.

As part of interface combination checking, verify any new
interface's beacon intervals. In fact, just always add the
beacon interval since that's harmless.
With this patch, mac80211 is prepared for drivers that set
the min_beacon_int_gcd parameter in interface combinations.
