TX FIFO size is 32k and it was divided into 256 pages with 128 bytes.
A boundary is used to split pages into two parts, head part is used to
store TX packets coming from host, and tail part is reserved for special
purposes, such as beacon packet, null data packet and so on.
The TX packets coming from host have many categories, such as VO, VI, BE,
BK, MG and etc. When going into head part of TX FIFO, they are classified
to four priority queue named low, normal, high and extra priority queues.
Each priority queue occupies predefined number of page, if a certain
priority queue is full, TX packet will store into PUB priority queue.
Similarly, RX FIFO is 16k and split into two parts, head part is used to
store RX packets, and tail part is 128 bytes and used to store report.
Thus, we fill this boundary to register as well.

The txagc table is used to map rate_id and txagc register address and
mask, and ops set_tx_power_index uses this table to write TX power to
corresponding registers. Since 8723D is a 1x1 2.4G 11n chip, only CCK, OFDM
and HT_MCS 0-7 are listed in the table.

H2C queue is used to send command to firmware. Since 8723D doesn't support
this queue, this commit check wlan_cpu flag to avoid to set H2C related
registers.

The power polling command is one kind of power sequence commands. It's used
to check hardware situation, and subsequent comamnds will be executed if
hardware is ready. A special case is PCIE must toggle BIT_PFM_WOWL and try
again if first try is failed.
In order to reduce indentation to understand the code easier, move polling
part to a separate function. Then, the 'while (1)...loop' is replaced by
two statements to do first try and retry.

The mac power-on flow consists of three steps:
1. pre_sys_cfg (Before switching power state)
2. power_switch (Switching power state)
3. init_sys_cfg (Settings after swtiching power state)
When switching power state, driver will load and parse the power sequence
tables. For 8723D devices, the logics for parsing are most same except for
the polling function. 8723D devices need to toggle BIT_PFM_WOWL twice.
The settings after power state is switched for 8723D devices are quite
different with other devices, extract a legacy function for them.
For power-off flow, 8723D devices have the same logic with existing chips.
But warning printed if we run power-off sequence in power-off state:
rtw_pci 0000:03:00.0: failed to poll offset=0x5f8 mask=0xff value=0x0
The scenario is user do 'ifconfig up' that will run power-on sequence to
bring up and then run power-off sequence to enter idle
(IEEE80211_CONF_IDLE). Then, user do 'ifconfig down' that will run
power-off sequence again, and the warning is shown. Original code check
power-on state to avoid to run power-on sequence twice, and this commit
extends to check both power-on and power-off states.

The firmware of 11AC devices need more information to support more offload
functions, such as IQK. And 11N devices such as 8723D does not support
offload these function in firmware, there is no need to send these additional
information to firmware when it comes to 11N devices.

The WLAN CPU of 8723D device is different from others, add legacy
firmware download function for it. A new variable wlan_cpu is used to
decide which firmware download function we should use.
Legacy firmware file contains 32 bytes header including version and
subversion. When downloading to wlan cpu, header is excluded.
Firmware is downloaded via beacon queue to reserved page that is a part of
TX buffer. Since 11N WLAN CPU uses different control registers, this patch
introduces related control registers.

When station connected to AP, and run TX traffic such as TCP/UDP, and
system enter suspend state, then mac80211 call ath10k_flush with set
drop flag, recently it only send wmi peer flush to firmware and
firmware will flush all pending TX packets, for PCIe, firmware will
indicate the TX packets status to ath10k, and then ath10k indicate to
mac80211 TX complete with the status, then all the packets has been
flushed at this moment. For SDIO chip, it is different, its TX
complete indication is disabled by default, and it has a tx queue in
ath10k, and its tx credit control is enabled, total tx credit is 96,
when its credit is not sufficient, then the packets will buffered in
the tx queue of ath10k, max packets is TARGET_TLV_NUM_MSDU_DESC_HL
which is 1024, for SDIO, when mac80211 call ath10k_flush with set drop
flag, maybe it have pending packets in tx queue of ath10k, and if it
does not have sufficient tx credit, the packets will stay in queue
untill tx credit report from firmware, if it is a noisy environment,
tx speed is low and the tx credit report from firmware will delay more
time, then the num_pending_tx will remain > 0 untill all packets send
to firmware. After the 1st ath10k_flush, mac80211 will call the 2nd
ath10k_flush without set drop flag immediately, then it will call to
ath10k_mac_wait_tx_complete, and it wait untill num_pending_tx become
to 0, in noisy environment, it is esay to wait about near 5 seconds,
then it cause the suspend take long time.

The default credit size is 1792 bytes, but the IP mtu is 1500 bytes,
then it has about 290 bytes's waste for each data packet on sdio
transfer path for TX bundle, it will reduce the transmission utilization
ratio for data packet.
This patch enable the small credit size in firmware, firmware will use
the new credit size 1556 bytes, it will increase the transmission
utilization ratio for data packet on TX patch. It results in significant
performance improvement on TX path.
This patch only effect sdio chip, it will not effect PCI, SNOC etc.

The transmission utilization ratio for sdio bus for small packet is
slow, because the space and time cost for sdio bus is same for large
length packet and small length packet. So the speed of data for large
length packet is higher than small length.
Test result of different length of data:
data packet(byte) cost time(us) calculated rate(Mbps)
256 28 73
512 33 124
1024 35 234

14336 168 682
28672 333 688
57344 660 695
This patch change the TX packet from single packet to a large length
bundle packet, max size is 32, it results in significant performance
improvement on TX path.
Also there's a fourth thread "ath10k_tx_complete_wq" added to ath10k as it
improves TCP RX throughput (values in Mbps):
TCP-RX TCP-TX UDP-RX UDP-TX
use workqueue_tx_complete 423 357 448 412
change it to ar->workqueue 410 360 449 414

8723D use SIPI to indirectly read RF register instead of directly read,
so introduce a new struct rtw_rf_sipi_addr and new function
rtw_phy_read_rf_sipi(). Since other chips don't use the new function,
only 8723D needs to fill struct rtw_rf_sipi_addr in rtw_chip_info.
Because there are two kinds of functions for reading RF registers now,
change rtw_phy_read_rf() to chip->ops->read_rf() in
rtw_phy_write_rf_reg_sipi() so that we can switch tp proper RF read
functions depends on the type of the chip.
Though 8723D is an 1x1 chip, it has two RF PHY and we can switch to
one of them, and that should be configured properly. Hence, add a
fix_rf_phy_num to struct rtw_chip_info to allow driver to set one of
the PHY's registers for 8723D, even it is only 1x1. Another variable
rf_phy_num is introduced to keep the constraint number of RF path we
can access, and its value is:
rf_phy_num = (fix_rf_phy_num ? fix_rf_phy_num : rf_path_num)

In the reference BIOS implementation, WRDS can be disabled without
disabling WGDS. And this happens in most cases where WRDS is
disabled, causing the WGDS without WRDS check and issue an error.
To avoid this issue, we change the check so that we only considered it
an error if the WRDS entry doesn't exist. If the entry (or the
selected profile is disabled for any other reason), we just silently
ignore WGDS.

The function iwl_mvm_remove_inactive_tids() returns bool, so we
should just check "if (ret)", not "if (ret >= 0)" (which would
do nothing useful here). We obviously therefore cannot use the

the queue (i) we're currently dealing with instead.

Due to some hardware issues, queue 31 isn't usable on devices that have
32 queues (7000, 8000, 9000 families), which is correctly reflected in
the configuration and TX queue initialization.
However, the firmware API and queue allocation code assumes that there
are 32 queues, and if something actually attempts to use #31 this leads
to a NULL-pointer dereference since it's not allocated.
Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also
add some code to catch this earlier in the future, if the configuration
changes perhaps.

In the context info, we need to indicate the correct RB size
to the device so that it will not think we have 4k when we
only use 2k. This seems to not have caused any issues right
now, likely because the hardware no longer supports putting
multiple entries into a single RB, and practically all of
the entries should be smaller than 2k.
Nevertheless, it's a bug, and we must advertise the right
size to the device.
Note that right now we can only tell it 2k vs. 4k, so for
the cases where we have more, still use 4k. This needs to
be fixed by the firmware first.

The iwl_trans_pcie_dyn_txq_free() function only releases the frames
that may be left on the queue by calling iwl_pcie_gen2_txq_unmap(),
but doesn't actually free the DMA ring or byte-count tables for the
queue. This leads to pretty large memory leaks (at least before my
queue size improvements), in particular in monitor/sniffer mode on
channel hopping since this happens on every channel change.
This was also now more evident after the move to a DMA pool for the
byte count tables, showing messages such as

The _hif_ prefix should be used only on functions part of ath10k_hif_ops, so
remove it from functions which should not have it.

This patch is to set register to allow the mbox enter sleep status
if it does not have tx traffic and wakeup it if tx traffic arrive.
After mbox enter sleep status, the soc will enter sleep status by
firmware, this will save power. The power consume drops from about
90mW to about 10mW with this patch.
This patch only effect sdio chip.
Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

Convert ath10k_hif_swap_mailbox() to a more generic op so that bus drivers can
do more than just swap the mailbox, for example set power save settings like in
the following sdio patch.

This function actually needs no return value. So remove the unneeded
variable 'ret' and make it void.
This also fixes the following coccicheck warning:
drivers/net/wireless/intel/ipw2x00/ipw2200.c:10648:5-8: Unneeded
variable: "ret". Return "0" on line 10684

User space program such as iw can set antenna mask for the device.
So add set antenna support by configure the trx mode.
This is useful for some tests want to see the output of different
antenna configuration (e.g. path A v.s. path B).
