Larry Finger 8334ffdc82 rtlwifi: Add explicit values to hw_variables enum
The entries in this enum may be referenced in debug output. Adding explicit
values simplifies the lookup.

Arnd Bergmann 08aba42fcc rtlwifi: use s8 instead of char
Compiling the rtlwifi drivers for ARM with gcc -Wextra warns about lots of
incorrect code that results from 'char' being unsigned here, e.g.

This patch changes all uses of 'char' in this driver that refer to
8-bit integers to use 's8' instead, which is signed on all architectures.

Johannes Berg 57fbcce37b cfg80211: remove enum ieee80211_band
This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

Larry Finger c18d8f5095 rtlwifi: rtl8723be: Add antenna select module parameter
A number of new laptops have been delivered with only a single antenna.
In principle, this is OK; however, a problem arises when the on-board
EEPROM is programmed to use the other antenna connection. The option
of opening the computer and moving the connector is not always possible
as it will void the warranty in some cases. In addition, this solution
breaks the Windows driver when the box dual boots Linux and Windows.

A fix involving a new module parameter has been developed.  This commit
adds the new parameter and implements the changes needed for the driver.

Larry Finger 73fb270592 rtlwifi: Fix size of wireless mode variable
Smatch reports the following warning:

  CHECK   drivers/net/wireless/realtek/rtlwifi/rc.c
drivers/net/wireless/realtek/rtlwifi/rc.c:144 _rtl_rc_rate_set_series() warn: impossible condition '(wireless_mode == 256) => (0-255 == 256)'

This warning arises because commit acc6907b87a9 ("rtlwifi: Fix warning
from ieee80211_get_tx_rates() when using 5G") now checks the wireless
mode for WIRELESS_MODE_AC_ONLY (BIT(8)) in _rtl_rc_rate_set_series().
As a result, all quantities used to store the wireless mode must be u16.

This patch also reorders struct rtl_sta_info to save a little space.

Colin Ian King ce2542435a rtlwifi: pass struct rtl_stats by reference as it is more efficient
passing rtl_stats by value is inefficient; the structure is over 300
bytes in size and generally just one field (packet_report_type)
is being accessed, so the pass by value is a relatively large overhead.
This change just affects just the rx_command_packet calls.

Larry Finger 0a44b22009 rtlwifi: rtl8821ae: Convert driver to use common 5G channel table
There are several copies of the 5G channel tables in this driver. These
are removed so that the tables in the core will be used. This change
also removes a useless message of "Channel 163 in Group not found".

The number of possible 5G channels was reduced from 54 to a better
value of 49 during the conversion.

Kalle Valo says:

====================
here's a bigger pull request for 4.4. The diffstat looks scary as we
created a new directory realtek for all realtek drivers. In the future
I'm planning to create similar directories for all vendors, currently we
just have ath, mediatek and realtek. This change has been in linux-next
for a couple of weeks so it should be safe, but of course you never
know.

There's also a new driver rtl8xxxu for few realtek USB devices. This
just made it to the last linux-next build.

Otherwise there's nothing really special, more info below. If time
permits, and it's ok for you, I'm hoping to send you a one more pull
request this week.

Larry Finger f1d2b4d338 rtlwifi: rtl818x: Move drivers into new realtek directory
Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.
