rtl818x_pci: handle broken PIO mapping
All boards supported by this driver could work using PIO or MMIO for accessing
registers.
This driver tries to access HW by using MMIO, and, if this fails for somewhat
reason, the driver tries to fall back to PIO mode.
MMIO-mode is straightforward on all boards.
PIO-mode is straightforward on rtl8180 only.
On rtl8185 and rtl8187se boards not all registers are directly available in PIO
mode (they are paged).
On rtl8185 there are two pages and it is known how to switch page.
PIO mode works, except for only one access to a register out of default page,
recently added by me in the initialization code with patch:
rtl818x_pci: Fix rtl8185 excessive IFS after CTS-to-self
This can be easily fixed to work in both cases (MMIO and PIO).
On rtl8187se, for a number of reasons, there is much more work to do to fix PIO
access.
PIO access is currently broken on rtl8187se, and it never worked.
This patch fixes the said register write for rtl8185 and makes the driver to
fail cleanly if PIO mode is attempted with rtl8187se boards.
While doing this, I converted also a couple of printk(KERN_ERR) to dev_err(), in
order to make checkpatch happy.

rtl8180: disable buggy rate fallback mechanism
Currently the driver configures mac80211 to provide two rates for each TX frame:
One initial rate and one alternate fallback rate, each one with its retry count.
HW does not support fully this: rtl8180 doesn't have support for rate scaling at
all, and rtl8185/rtl8187SE supports it in a way that does not fit with mac80211:
The HW does automatically fall back to the next lower rate, and only a lower
limit can be specified, so the HW may TX also on rates in between the two rates
specified by mac80211. Furthermore only the total TX retry count can be
specified for each packet, while the number of TX attempts before scaling rate
can be configured only globally (not per each packet).
Currently the driver sets the HW auto rate fallback mechanism to quickly scale
rate after a couple of retries, and it uses the alternate rate requested by
mac80211 as fallback limit rate (and it does this even wrongly).
The HW indeed will behave differently than what mac80211 mandates, that is
probably undesirable, and the reported TX retry count may not refer to what
mac80211 thinks, and this could fool mac80211.
This patch makes the driver to declare to mac80211 to support only one rate
configuration for each packet, and it does disable the HW auto rate fallback
mechanism, relying only on SW and letting mac80211 to do all by itself.
This should ensure correct operation and fairness respect to mac80211.
Indeed here tests with iperf do not show significant performance differences.

rtl8180: fix incorrect TX retry.
HW is programmed with wrong retry count value for TX:
Mac80211 passes to driver the number of times the TX should be attempted.
The HW, instead, wants the number of time the TX should be retried if it fails
the first time (assuming we have to TX it at least one time).

rtl818x_pci: add comment pointing to the rtl8187se reference code
Rtl8187se support has been added to the rtl818x_pci driver by extracting a lot
of information from a rtl8187se Linux staging driver included in the kernel at
the time rtl8187se support was added.
The rtl818x_pci main file has a comment that advertises this.
Recently this staging driver has been removed from the kernel, but I still feel
it can be useful as "reference" code (in case of bugs, or to implement
improvements in rtl818x_pci driver).

rtl818x_pci: Fix rtl8185 excessive IFS after CTS-to-self
Measuring time between _end_ of CTS-to-self and _end_ of datapacket (with a
prism54 board and mac80211 hacked to let the MAC timestamp stay untouched in the
radiotap header) resulted in about 300uS, while the datapacket itself should be
by far shorter (less than 100uS) and IFS should be SIFS (10uS).
This measure was confirmed whith a scope: about 250uS IFS has been seen between
the two packets.
This situation causes the CTS-to-self protection mechanism to work incorrectly
due to the NAV expiring during, or even before beginning, the packet
transmission, and it also causes the performances to be anyway reduced due to
time waste.
This problem has been seen at every packet TXed with CTS-to-self enabled on
rtl8185 board.
rtl8187se seems not affected (and rtl8180, being a 802.11b card, does not have
CTS-to-self mechaninsm).
This patch fixes this by adding a magic register write, making the board wait
for correct SIFS after CTS-to-self packet.

net/wireless/brcm80211/brcmfmac: Make return type and name reflect actual semantics
Applying ++ to a bool is equivalent to setting it true, regardless of
its initial value (bools are not uint1_t). Hence the function
wl_get_vif_state_all can only ever return true/false. The only in-tree
caller uses its return value as a boolean. So update its return type,
and since the list traversal and bit testing have no side effects,
just return true immediately. Its return value tells if any vif is in
the specified state, so also rename it to brcmf_get_vif_state_any.

mwifiex: print sleep_confirm cmd/response and power save events
Sleep Confirm command is sent separately while other commands
are handled through cmd_pending_q. Print sleep_confirm cmd and
its response as well as power save events so that we have a
clearer picture of power save handshake in driver log.

mwifiex: add hscfg to debugfs
Some SDIO controllers do not support MMC_PM_KEEP_POWER properly.
To test host sleep feature without putting the system into sleep
we need to simulate host sleep configuration & handshake between
driver and firmware using customized parameters.
This patch adds hscfg debugfs item, with which user could change
host sleep parameters for debugging.

mwifiex: add firmware dump feature for SDIO
Firmware dump feature is added for SDIO based chipsets
which can be used with the help of ethtool commands.
1) Trigger firmware dump operation:
ethtool --set-dump mlan0 0xff
When the operation is completed, udev event will be sent to
trigger external application.
2) Following udev rule can be used to get the data from ethtool:
DRIVER=="mwifiex_sdio", ACTION=="change", RUN+="/sbin/mwifiex_sdio_fw_dump.sh"
mwifiex_sdio_fw_dump.sh: #!/bin/bash
