ebe6c7ba9b mac80211: Fix radiotap header it_present on big endian CPUs
When the IEEE80211_RADIOTAP_RATE flag was moved to be conditional, it
was mistakenly left without cpu_to_le32(). Fix that.

Since we do not currently report HT rates (MCS index) in radiotap

133b822638 mac80211: make master iface not wireless
There's no need to register the master netdev with cfg80211,
in fact, this is quite dangerous and lead to having to add
checks for the master interface all over the config handlers.
This patch removes the "ieee80211_ptr" from the master iface
in favour of having a small netdev_priv() associated with
the master interface that stores the ieee80211_local pointer.
Because of this, a lot of code in the configuration handlers
can go away. To make this patch easier to verify I have also
removed a number of wiphy_priv() calls in favour of getting
the sdata first and then the local pointer from that.

This patch address some IBSS rate issues introduced or not covered
by "mac80211: eliminate IBSS warning in rate_lowest_index()" and
"cfg80211 API for channels/bitrates, mac80211 and driver conversion".

This patch:
1. Moves addition of IBSS station from
prepare_for_handlers to ieee80211_rx_bss_info when triggered from beacon
eliminating bogus supported rates.
2. Initialize properly supported rates also in IBSS merging
3. Ensure that mandatory rates are always added into supported
rates. This is needed in case when station addition is triggered from
non beacon/probe packet. Some management frames need to be sent
4. Remove initialization of supported rates from self rates. This path
was dead code after 6bc37c06bc4 and in general incorrect.

f698d856f6 replace net_device arguments with ieee80211_{local,sub_if_data} as appropriate
This patch replaces net_device arguments to mac80211 internal functions
with ieee80211_{local,sub_if_data} as appropriate.

It also does the same for many 802.11s mesh functions, and changes the
mesh path table to be indexed on sub_if_data rather than net_device.

If the mesh part needs to be a separate patch let me know, but since
mesh uses a lot of mac80211 functions which were being converted anyway,
the changes go hand-in-hand somewhat.

This patch probably does not convert all the functions which could be
converted, but it is a large chunk and followup patches will be
provided.

3e122be089 mac80211: make master netdev handling sane
Currently, almost every interface type has a 'bss' pointer
pointing to BSS information. This BSS information, however,
is for a _local_ BSS, not for the BSS we joined, so having
it on a STA mode interface makes little sense, but now they
have it pointing to the master device, which is an AP mode
virtual interface. However, except for some bitrate control
data, this pointer is only used in AP/VLAN modes (for power
saving stations.)

Overall, it is not necessary to even have the master netdev
be a valid virtual interface, and it doesn't have to be on
the list of interfaces either.

This patch changes the master netdev to be special, it now
 - no longer is on the list of virtual interfaces, which
   lets me remove a lot of tests for that
 - no longer has sub_if_data attached, since that isn't used

Additionally, this patch changes some vlan/ap mode handling
that is related to these 'bss' pointers described above (but
in the VLAN case they actually make sense because there they
point to the AP they belong to); it also adds some debugging
code to IEEE80211_DEV_TO_SUB_IF to validate it is not called
on the master netdev any more.

f4ea83dd74 mac80211: rework debug settings and make debugging safer
This patch reworks the mac80211 debug settings making them more focused
and adding help text for those that didn't have one. It also removes a
number of printks that can be triggered remotely and add no value, e.g.
"too short deauthentication frame received - ignoring".

If somebody really needs to debug that they should just add a monitor
interface and look at the frames in wireshark.

49461622ed mac80211: get rid of function pointers in RX path
This changes the RX path to no longer use function pointers for
RX handlers but rather invoke them directly. If debugging is
enabled, mark the RX handlers noinline because otherwise they
all get inlined into ieee80211_invoke_rx_handlers() which makes
it harder to see where a bug is.

87291c0269 mac80211: eliminate IBSS warning in rate_lowest_index()
In IBSS mode prior to join/creation of new IBSS it is possible that
a frame from unknown station is received and an ibss_add_sta() is
called. This will cause a warning in rate_lowest_index() since the
list of supported rates of our station is not initialized yet.

The fix is to add ibss stations with a rate we received that frame
at; this single-element set will be extended later based on beacon
data. Also there is no need to store stations from a foreign IBSS.
