Larry Finger f3355dd9f7 rtlwifi: rtl8192ce: rtl8192cu: rtl8192de: rtl8192se: rtl8723ae: rtl8723be: rtl8188eu: Modify for new API
The addition of a driver for the RTL8821AE requires a new API for the
fill_tx_desc() and set_desc() callback routines. This commit makes the
appropriate modifications in all the other drivers.

Johannes Berg d8ca16db6b mac80211: add length check in ieee80211_is_robust_mgmt_frame()
A few places weren't checking that the frame passed to the
function actually has enough data even though the function
clearly documents it must have a payload byte. Make this
safer by changing the function to take an skb and checking
the length inside. The old version is preserved for now as
the rtl* drivers use it and don't have a correct skb.

Karl Beldan 675a0b049a mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chan
Drivers that don't use chanctxes cannot perform VHT association because
they still use a "backward compatibility" pair of {ieee80211_channel,
nl80211_channel_type} in ieee80211_conf and ieee80211_local.

Johannes Berg e1a0c6b3a4 mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40
For VHT, many more bandwidth changes are possible. As a first
step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag
in the HT capabilities and instead introduce a bandwidth field
indicating the currently usable bandwidth to transmit to the
station. Of course, make all drivers use it.

To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get
the station as an argument, rather than the new capabilities,
so it can set up the new bandwidth field.

If the station is a VHT station and VHT bandwidth is in use,
also set the bandwidth accordingly.

Doing this allows us to get rid of the supports_40mhz flag as
the HT capabilities now reflect the true capability instead of
the current setting.

While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not
ignore HT cap overrides when MCS TX isn't supported (not that it
really happens...)

Larry Finger 0bd899e764 rtlwifi: rtl8192c: rtl8192ce: Add support for B-CUT version of RTL8188CE
Realtek devices with designation RTL8188CE-VL have the so-called B-cut
of the wireless chip. This patch adds the special programming needed by
these devices. In addition, a variable that was static has been moved into
the private data area as it is now needed in two different routines. This
change also fixes a minor bug that would be present if a system had more
than one RTL81{88,92}CE devices. Other drivers in the rtlwifi family had
already made this change, thus the variable already exists in the private
data structure.

Joe Perches 2c208890c6 wireless: Remove casts to same type
Adding casts of objects to the same type is unnecessary
and confusing for a human reader.

For example, this cast:

        int y;
        int *p = (int *)&y;

I used the coccinelle script below to find and remove these
unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

@@
type T;
T *p;
@@

-       (T *)p
+       p

Neatened the mwifiex_deauthenticate_infra function which
was doing odd things with array pointers and not using
is_zero_ether_addr.
