This patch adds support for dropping gratuitous ARP frames which is
requirement for WFA Hotspot2.0.
Hotspot2.0 capability is enabled in driver if extended capabilities
IE from BSS descriptor has 11u interworking enabled.

EXT_CAPAB_IE format involves IEEE header followed by bytestream of
capabilities. Current structure has incorrect member u8 for data;
fix it by defining it as u8[0].

This patch fixes an issue where RX throughput values observed
were substantially lower than TX counterparts for PCIe8897 STA.
PCIe8897 supports larger rx_win_size. After changing these values
we see big improvement for TX and RX throughput values.
Different tx_win_size and rx_win_size are used for AP mode.
All BA setup related initialization has been moved to separate
function.

For STA mode, collect VHT realated IEs from the Beacons or Probe
Responses and append similar VHT related IEs to association
requests.
For AP mode, get VHT related capability information and share it
with cfg80211 at the time of wiphy register. This information is
further used by cfg80211 and hostapd to start an AP with 802.11AC
support.
Currently only 8897 supports 802.11AC.

alloc failures already get standardized OOM
messages and a dump_stack.
Convert kzalloc's with multiplies to kcalloc.
Convert kmalloc's with multiplies to kmalloc_array.
Remove now unused variables.
Remove unnecessary memset after kzalloc->kcalloc.
Whitespace cleanups for these changes.

It's observed that reconfiguration of tx buffer size before
association can cause data path failure in firmware after
associated. Although this is only found with PCIe cards, but
potentially it could happen with any other interfaces as well.
The tx buffer reconfiguration is not really useful in firmware.
Let's remove it for all interfaces.

It is observed that same htcapinfo ie is included in beacon for
HT20, HT40+ and HT40- ibss networks. This patch makes sure that
we will not advertise 40Mhz flags while creating/joining ibss
network in HT20 mode.

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.

Since some of the HT code pre-dates 802.11n-2009
some names are wrong. The one that bothers me most
is that "HT operation" is called "HT information"
in our code and that causes confusion.
Rename "HT information" to "HT operation" and also
the control_chan field to primary_chan to match
the name used in the spec.

In some cases local pointers are used to cast void pointers passed to
the function. Those unnecessary local pointers are also removed.
This patch was inspired by Joe Perches' patch
[PATCH net-next 1/2] wireless: Remove casts of void *;
and the comments from Julian Calaby.

1) Initialise HT capabilities in cfg80211 properly.
2) Cfg80211 stack may modify "sband->ht_cap" to disable
40Mhz operation in 2.4GHz band (after recent patch
"cfg80211: module_param to disable HT40 in 2.4GHz band")
Therefore read "sband->ht_cap" instead of an adapter variable
"hw_dot_11n_dev_cap" to get HT capabilities.

2) avoid dynamic allocation of wait queue
3) remove unnecessary mwifiex_error_code macros that
were used mainly by the wait queue status code
4) remove some abstraction functions
5) split mwifiex_prepare_cmd() to mwifiex_send_cmd_async()
and mwifiex_send_sync() to handle asynchronous and
synchronous commands respectively

The hw_dot_11n_dev_cap reported by firmware hw_spec
has different format than the 11n capabilities.
Hence a lot of SET_ and RESET_ bit operation macros
were used to convert the dev_cap format to 11n
capability format. However the locally defined 11n
ht_cap macros are not necessary as we can use
IEEE80211_HT_CAP_ macros directly.
The 32-bit dev_cap bitmap is added as comment to
explain the mapping between firmware and 11n spec.
Some unused macros and unnecessary adapter variables
are also removed.
