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

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.

Measuring time between _end_ of CTS-to-self and _end_ of datapacket (with a

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

rtl8187se seems not affected (and rtl8180, being a 802.11b card, does not have

mac80211: use chanctx reservation for AP CSA
Channel switch finalization is now 2-step. First
step is when driver calls csa_finish(), the other
is when reservation is actually finalized (which
can be deferred for in-place reservation).
It is now safe to call ieee80211_csa_finish() more
than once.

mac80211: split sched scan IEs
Split sched scan IEs to band specific and not band specific
blocks. Common IEs blocks may be sent to the FW once per command,
instead of per band.
This allows optimization of size of the command, which may be
required by some drivers (eg. iwlmvm with newer firmware version).
As this changes the mac80211 API, update all drivers to use the
new version correctly, even if they don't (yet) make use of the
split data.

mac80211: support more than one band in scan request
Some drivers (such as iwlmvm) can handle multiple bands in a single
HW scan request. Add a HW flag to indicate that the driver support
this. To hold the required data, create a separate structure for
HW scan request that holds cfg scan request and data about
different parts of the scan IEs.
As this changes the mac80211 API, update all drivers using it to
use the correct new function type/argument.

iwlwifi: mvm: Introduce an API to set STA_FLG_DISABLE_TX flag
Introduce new station flag STA_FLG_DISABLE_TX, which is modified with ADD_STA
command. This flag, when set, disables tx to the STA.
Provide an API (iwl_mvm_sta_modify_disable_tx) to modify this flag, which
should be used in channel switch and immediate quiet flows.

iwlwifi: mvm: disable beacon filtering escape timer in d0i3
The beacon filtering configuration in d0i3 currently uses
the max value defined as 1024. However, with beacon interval
of 100ms we end up with too-frequent wakeups.
Instead, configure the escape timer to 0, asking the fw
to disable it altogether.
iwlwifi: mvm: BT Coex - avoid the shared antenna for management frames
If BT is active, we need to refrain from using the shared
antenna. This logic is done in the firmware when we use the
link quality tables. But for management frames, the rate is
written in the Tx command by the driver.
Hence the driver needs to make sure not use the shared
antenna when BT is active for any frames that don't use
the rate scale table such as management frames or multicast.

We can Tx in MIMO rates when we are in TxTx Disallow mode
just like we can when we are in Tight mode.
Same if we are in 5Ghz regardless of the mode we are.
Change the code to allow MIMO in these cases.
