51117ed116 LinuxKPI: 802.11: correct HE_MAC_CAP3 values
While we had assigned dummy values so far to HE, correct the HW_MAC_CAP3
values to avoid compile time errors of drivers when shifting values out
of range.

Fix the sizing of IEEE80211_TX_INFO_DRIVER_DATA_SIZE so that it
also works on 32bit platforms.  Otherwise it triggers a compile-time

35f7fa4ac1 LinuxKPI: 802.11: improve assertion and tkip code
Move a KASSERT out of a function and make it a CTASSERT with
appropriate comments.

Skeleton implement two tkip functions, still left TODO, initializing
variables with dummy values to quiten compiler warnings.  It is
unclear to me if we should still ever properly implement TKIP
compat code at this point.  If so the current code gives a good
idea what needs to be done in addition to allocating references
to real state along with keyconf.

75388b9ca5 LinuxKPI: add (skeleton) functions to make drivers compile
Add more functions to netdevice.h (netif_napi_add_tx() being the only
one implemented) and add platform_device.h and netlink.h in order to
make driver code compile.
The skeleton functions are used only in very limited scope and not at
all in our usage so far but add (invasive) #ifdef if removed.
Add pr_debug() calls to each of them in order to log a TODO (if DEBUG
compiled in) and someone should hit them in the future.

5edde07c2a LinuxKPI: 802.11: implement cfg80211_{get,put}_bss
Implement cfg80211_{get,put}_bss currently doing malloc/free bits,
so hopefully the drivers get the calls right.

cfg80211_get_bss() sets up a lookup structure which may also take a
result (first hit wins) and calls ieee80211_scan_iterate() comparing
the various values in the iterator funcion.  Some of the checks are
partially pointless (as it seems the drivers are not interested in
these parts [ANY] but we keep them for documentation purposes should
futher values arise in the future).

We currently only iterate over the first VAP which will do for now.

Fix types for various struct fields (initially added as int).

Move structs and inline functions logically together, e.g., for wowlan.

Add struct ieee80211_vht_cap (without "_ie") to net80211 and remove
duplicate definitions in LinuxKPI headers now using net80211 structs.
For now leave ieee80211_ie_vhtcap in net80211.  I am not sure yet if we
actually need it as such.  That'll be cleaned up with more VHT updates
in net80211 in the future.

ec190d9150 LinuxKPI: 80211: improve linuxkpi_ieee80211_get_tid()
Continue what was started in 26a3694833
in iwlwifi and extend out internal implementation of
linuxkpi_ieee80211_get_tid() by an argument as to whether "no-QoS"
answers are acceptable.  For the LinuxKPI ieee80211_get_tid() set
this to false as the Linux derived drivers seem to do extra checks
for the QoS-Data frame before acquiring the tid.
Add KASSERTs to enforce the extra argument.
This allows us to use the net80211 variant in LinuxKPI for other
means explicitly documenting that we do accept a IEEE80211_NONQOS_TID.

caaa79c3f8 LinuxKPI 802.11: change type of bssid in struct ieee80211_bss_conf
Enabling other driver code found that the bssid in
struct ieee80211_bss_conf is not an array but expected to be
a const pointer (const, != NULL checks).
Adjust accordingly in the header and in the LinuxKPI compat code.
There initialization now needs to be a static array always present
as we need a value before we will have a BSS (node in scan_to_auth)
as the mac80211 driver (*handlers) are expecting the pointer to be
not NULL (copying without checks).
This is a pre-req to enable d3 (CONFIG_PM[_SLEEP]) in the future.
