c03e3fe91c ipw2x00: Remove a memory allocation failure log message 
Axe a memory allocation failure log message. This message is useless and
incorrect (vmalloc is not used here for the memory allocation)

This has been like that since the very beginning of this driver in
commit 43f66a6ce8 ("Add ipw2200 wireless driver.")

fd5d781964 rtw88: Use udelay instead of usleep in atomic context 
It's incorrect to use usleep in atomic context.

Switch to a macro which uses udelay instead of usleep to prevent the issue.

ea1b3bc6d5 brcmfmac: no need to check return value of debugfs_create functions 
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

In doing this, make brcmf_debugfs_add_entry() return void as no one was
even paying attention to the return value.

follow this guideline by default.

When the primary interface is set to a locally administered address, the

19f557a9b8 brcmfmac: remove arp_hostip_clear from brcmf_netdev_stop 
The firmware does not respond ARP request and causes ping failure with
following steps:

1. Bring up interface
   ifconfig wlan0 up or start wpa_supplicant
2. Set the IP address
   ifconfig wlan0 192.168.100.10
3. Bring down interface or
   ifconfig wlan0 down or kill wpa_supplicant
4. Bring up interface again and set the same IP address
5. Connect to AP(192.168.100.1) and ping to AP will be failed.

FMAC clears arp_hostip when bringing down the interface, but not set it
back if setting the same IP address. We are able to see the IP address
in interface info(inconfig wlan0) but the ping still cannot work because
the firmware ARP offload does not respond the ARP request.
Because of that, we remove "arp_hostip_clear" from function
"brcmf_netdev_stop"

4af119509a iwlwifi: move API version lookup to common code 
The API version lookup is parsed from a TLV and should be in shared code
make make it reusable across all opmodes.

Also change the function names from mvm to fw, since this is not
mvm-specific anymore.

Additionally, since this function is not just a single line of code, it
shouldn't be inline.  Convert them to actual functions.

d91277de23 rtw88: 8723d: Organize chip TX/RX FIFO 
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.

fd9ead3851 rtw88: decompose while(1) loop of power sequence polling command 
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.

4e223a5f53 rtw88: 8723d: Add mac power-on/-off function 
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 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.
