Xinming Hu cf5383b088 mwifiex: add manufacturing mode support
By default normal mode is chosen when driver is loaded. This
patch adds a provision to choose manufacturing mode via module
parameters.

Below command loads driver in manufacturing mode
insmod mwifiex.ko mfg_mode=1.

Shengzhen Li 3ee7128579 mwifiex: add get_antenna support for cfg80211
Since commit de3bb771f4 ("cfg80211: add more warnings for inconsistent
ops") the wireless core warns if a driver implements a cfg80211 callback
but doesn't implements the inverse operation.

The mwifiex driver defines a .set_antenna handler but not a .get_antenna
so this not only makes the core to print a warning when creating a new
wiphy but also the antenna isn't reported to user-space apps such as iw.

This patch queries the antenna to the firmware so is properly reported to
user-space. With this patch, the wireless core does not warn anymore and:

$ iw phy phy0 info | grep Antennas
        Available Antennas: TX 0x3 RX 0x3
        Configured Antennas: TX 0x3 RX 0x3

Amitkumar Karwar 437322ea2a mwifiex: fix system hang problem after resume
On some platforms, driver is unable to wakeup firmware after system resume
due to a problem at MMC subsystem. Triggering card reset in this case has
a race with card removal from MMC which causes system hang. This patch
resolves the problem by not triggering card reset.

Arnd Bergmann 2095b1426c mwifiex: fix link error against sdio
Calling sdio_claim_host() from the interface independent part of
the mwifiex driver is not only a layering violation, but also causes
a link error if MMC support is disabled, or if CONFIG_MMC=m
and CONFIG_MWIFIEX=y:

drivers/net/built-in.o: In function `mwifiex_fw_dpc':
:(.text+0xff138): undefined reference to `sdio_claim_host'
:(.text+0xff158): undefined reference to `sdio_release_host'

The right way to do this is to have the sdio specific code in the
sdio driver front-end, and we already have a callback pointer that
we can use for this after exporting the generic fw download
function from the core driver.

chunfan chen 2fd5c6ed0b mwifiex: firmware download enhancements
Same chip is being used by WLAN as well as bluetooth
drivers. Each driver needs to check during initialisation
if firmware is already active or it needs to be freshly
downloaded. If one driver has started downloading the
firmware, other finds the winner flag as false.

mwifiex_check_fw_status() checks firmware status and also
check if WLAN is the winner for firmware downloading.

Once we detect that other interface is downloading
the firmware, we call this routine again with max
poll count to wait until firmware is ready.

This patch splits the routine to avoid checking
winner status unnecessarily multiple times and ensures
that correct messages are displayed to user.

Firmware status poll count is also increased to 150.
