Lots of conflicts, by happily all cases of overlapping
changes, parallel adds, things of that nature.

Thanks to Stephen Rothwell, Saeed Mahameed, and others
for their guidance in these resolutions.

====================
This time we have too many changes to list, highlights:
 * virt_wifi - wireless control simulation on top of
   another network interface
 * hwsim configurability to test capabilities similar
   to real hardware
 * various mesh improvements
 * various radiotap vendor data fixes in mac80211
 * finally the nl_set_extack_cookie_u64() we talked
   about previously, used for
 * peer measurement APIs, right now only with FTM
   (flight time measurement) for location
 * made nl80211 radio/interface announcements more complete
 * various new HE (802.11ax) things:
   updates, TWT support, ...

mac80211: Properly access radiotap vendor data

2018-12-19T08:41:10+00:00

The radiotap vendor data might be placed after some other
radiotap elements, and thus when accessing it, need to access
the correct offset in the skb data. Fix the code accordingly.

mac80211: free skb fraglist before freeing the skb

2018-12-19T08:40:17+00:00

mac80211 uses the frag list to build AMSDU. When freeing
the skb, it may not be really freed, since someone is still
holding a reference to it.
In that case, when TCP skb is being retransmitted, the
pointer to the frag list is being reused, while the data
in there is no longer valid.
Since we will never get frag list from the network stack,
as mac80211 doesn't advertise the capability, we can safely
free and nullify it before releasing the SKB.

mac80211: fix radiotap vendor presence bitmap handling

2018-12-19T08:39:01+00:00

Due to the alignment handling, it actually matters where in the code
we add the 4 bytes for the presence bitmap to the length; the first
field is the timestamp with 8 byte alignment so we need to add the
space for the extra vendor namespace presence bitmap *before* we do
any alignment for the fields.

Move the presence bitmap length accounting to the right place to fix
the alignment for the data properly.

mac80211: do not advertise HE cap IE if HE disabled

2018-12-18T13:19:52+00:00

When disabling HE due to the lack of HT/VHT, do it
at an earlier stage to avoid advertising HE capabilities IE.
Also, at this point, no need to check if AP supports HE, since
it is already checked earlier (in ieee80211_prep_channel).

mac80211: set STA flag DISABLE_HE if HE is not supported

2018-12-18T13:19:39+00:00

Up until now, the IEEE80211_STA_DISABLE_HE flag was set only based
on whether the AP has advertised HE capabilities.
This flag should be set also if STA does not support HE
(regardless of the AP support).

mac80211: propagate the support for TWT to the driver

2018-12-18T13:18:49+00:00

TWT is a feature that was added in 11ah and enhanced in
11ax. There are two bits that need to be set if we want
to use the feature in 11ax: one in the HE Capability IE
and one in the Extended Capability IE. This is because
of backward compatibility between 11ah and 11ax.

In order to simplify the flow for the low level driver
in managed mode, aggregate the two bits and add a boolean
that tells whether TWT is supported or not, but only if
11ax is supported.
