On newer hardware, the tx_queue debugfs file would need to
allocate 37.5kib data since there are 512 queues, which is
too much. Rather than resorting to kludges like kvmalloc(),
use the seq_file API to print out the data.
While at it, also fix a NULL pointer dereference here, the
txq pointer from trans_pcie->txqs[] may be NULL if that
queue hasn't been allocated.

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 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.

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)

This patch fixes commit 75388acd0c ("add mac80211-based driver for
legacy BCM43xx devices")
In https://bugzilla.kernel.org/show_bug.cgi?id=207093, a defect in
b43legacy is reported. Upon testing, thus problem exists on PPC and
X86 platforms, is present in the oldest kernel tested (3.2), and
has been present in the driver since it was first added to the kernel.
The problem is a corrupted channel status received from the device.
Both the internal card in a PowerBook G4 and the PCMCIA version
(Broadcom BCM4306 with PCI ID 14e4:4320) have the problem. Only Rev, 2
(revision 4 of the 802.11 core) of the chip has been tested. No other
devices using b43legacy are available for testing.
Various sources of the problem were considered. Buffer overrun and
other sources of corruption within the driver were rejected because
the faulty channel status is always the same, not a random value.
It was concluded that the faulty data is coming from the device, probably
due to a firmware bug. As that source is not available, the driver
must take appropriate action to recover.
At present, the driver reports the error, and them continues to process
the bad packet. This is believed that to be a mistake, and the correct
action is to drop the correpted packet.

On some systems we can constanly see rtw88 complains:
[39584.721375] rtw_pci 0000:03:00.0: failed to send h2c command
Increase interval of each check to wait the status bit really changed.
Use read_poll_timeout() macro which fits anything we need here.

This patch adds the AirVasT USB wireless devices 124a:4026
to the list of supported devices. It's using the ISL3886
usb firmware. Without this modification, the wiki adapter
is not recognized.
