Commit a619d1abe20c leads to the following static checker warning:
drivers/net/wireless/rtlwifi/rtl8723be/phy.c:667 _rtl8723be_store_tx_power_by_rate()
error: buffer overflow 'rtlphy->tx_power_by_rate_offset[band]' 4 <= 5
This warning arises because the code is testing the indices for the wrong maximum
values. In addition, the tests merely putput a warning, and then procedes to
corrupt memory. With this change, any such invalid memory access is avoided.

and added "_ieee80211_is_robust_mgmt_frame" as a direct replacement

We can now define the priority against BT per AC. This is
possible with a newer firmware that allows to define the
priority with 2 bits.
Note that this change is compatible with older firmware
since older firmware will simply ignore the new bit (11),
and we still set the old bit (12) in the same cases as
before.

This code is really related to BT Coex - move it to the coex
file.
Also - prepare for a FW API change that will happen soon:
Bits 11 and 12 will be allocated for BT priority. Today, we

7265 features a new calibration which is called antenna
coupling. The purpose of this calibration (which isn't
really a calibration), is to measure the isolation between
the antennas and that can give us useful information for
the Coex modules.
With this information, we can tune the LookUpTables (LUTs)
that define the BT / WiFi contention policy.
The LUTs currently contain dummy values - but they will be
updated soon.
While at it, change the current code to stop duplicate the
host command while sending. This was needed back then, when
the command was short enough to be allocated on the stack.
Since then, the command grew a lot and is now allocated on
the heap - hence we can use the NOCOPY option instead.

There is a flow in which we send the host command in SYNC

A scheduled scan is a more persistent setting and should take priority
over temporary regular scans. Abort the regular when a sched_scan
request arrives and then request the sched_scan.
The kernel API allows sending a sched_scan without canceling a regular
scan in progress, so this is our way to abstract the FW's limitations.
Make the scan-cancel Rx handler async and flush after invocation to
ensure new scans can't creep in before it.

cfg80211 assumes a scheduled scan is stopped synchronously. Wait for the
FW before returning to caller.
Don't do anything in the async handler in the stop-from-above flow.
There's no need to call the mac80211 sched-scan completion as the
cleanup will be automatic. Make sure the async handler is called before
the next incoming scan changes the scan_status by flushing the async
handlers after all invocations.

When indicating RF-kill toggle to the higher layer, that
may in turn call back to the transport (for MVM at least)
to turn off the device quickly. Instead of that, allow it
to return whether or not the device should be turned off,
this gets rid of the call indirection and will help make
the API more consistent when we go back to non-threaded
interrupts again for PCIe.

1. Enable LP XTAL to avoid HW bug where device may consume much
power if FW is not loaded after device reset. LP XTAL is
disabled by default after device HW reset. Configure device's
"persistence" mode to avoid resetting XTAL again when SHRD_HW_RST
occurs in S3.
2. Add methods to access SHR (shared block memory space) directly from PCI
bus w/o need to power up MAC HW.
Shared internal registers (e.g. SHR_APMG_GP1, SHR_APMG_XTAL_CFG)can be
accessed directly from PCI bus through SHR arbiter even when MAC HW is
powered down. This is possible due to indirect read/write via
HEEP_CTRL_WRD_PCIEX_CTRL (0xEC) and HEEP_CTRL_WRD_PCIEX_DATA (0xF4)
registers.
Use iwl_write32()/iwl_read32() family to access these registers. The MAC HW
need not be powered up so no "grab inc access" is required.
For example, to read from SHR_APMG_GP1 register (0x1DC),
first, write to the control register:
HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register)
HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 2 (read access)
second, read from the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0].
To write the register, first, write to the data register
HEEP_CTRL_WRD_PCIEX_DATA[31:0] and then:
HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register)
HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 3 (write access)

When power update is initiated on BSS STA while P2P client
exists, the power command will be sent only on BSS STA vif
ignoring P2P client.
Since the firmware has symmetric constraints on the power
save enablement we can simplify the code a bit.
The current firmware doesn't know how to enable power
management on P2P client. Even BSS power management must
be disabled when a P2P client is added.
Future firmware will support power save on BSS and P2P client
as long as they are on different channels.
This was buggy since we didn't disable power management on
P2P client interface if BSS added on the same channel.

iwlegacy version of this iwlwifi patch:
commit aed7d9ac1836defe033b561f4306e39014ac56fd
Author: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Wed Feb 20 11:33:00 2013 +0200
iwlwifi: disable 8K A-MSDU by default
Supporting 8K A-MSDU means that we need to allocate order 1
pages for every Rx packet. Even when there is no traffic.
This adds stress on the memory manager. The handling of
compound pages is also less trivial for the memory manager
and not using them will make the allocation code run faster
although I didn't really measure.
Eric also pointed out that having huge buffers with little
data in them is not very nice towards the TCP stack since
the truesize of the skb is huge. This doesn't allow TCP
to have a big Rx window.
See https://patchwork.kernel.org/patch/2167711/ for details.
Note that very few vendors will actually send A-MSDU.
Disable this feature by default.
