Only rtl8821ae implements WOWLAN; however, the other drivers may receive
a call requesting information about this mode. The other drivers need to
ignore the request rather than logging that the default branch of the

As soon as debugging is turned on, the logs are filled with messages
reporting the interrupt status. As this quantity is usually zero, this
output is not needed. In fact, there will be a report if the status is
not zero, thus the debug line in question could probably be deleted.
Rather than taking that action, I have changed it to only be printed
when the newly added RTL8XXXU_DEBUG_INTERRUPT bit is set in the debug
mask.

It's been observed that in a corner case mwifiex_usb_tx_complete()

In mwifiex_usb_tx_complete(), we are updating port->block_status first
and then freeing the skb attached to that URB. We may end up attaching
new skb to URB in a corner case and same will be freed. This results in
the kernel crash. The problem is solved by changing the sequence.

Booting multiple wl12xx and wl18xx devices using the same rootfs is
a pain. You currently have to symlink the right nvs file depending
on the wl12xx type.
For example, with wl1271-nvs.bin being a symlink to wl127x-nvs.bin
by default and trying to bring up a wl128x based device:
wlcore: ERROR nvs size is not as expected: 1113 != 912
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR firmware boot failed despite 3 retries
Note that wl18xx uses a separate config firmware wl18xx-conf.bin
that can be generated with tools using the following two git repos:
git.ti.com/wilink8-wlan/18xx-ti-utils
git.ti.com/wilink8-wlan/wl18xx_fw
So let's not configure the nvs file for wl18xx as it's not needed
AFAIK. If it turns out that we also need the nvs file for wl18xx,
we can just add it to the config firmware data for wl18xx.
Let's fix the issue by using the chip specific config firmware
data, and make sure we produce understandable warnings if something
is missing.

In order to access cached/paged memory, there are a couple of firmware
commands (one for UMAC and one for LMAC) that let the host access memory
and registers indirectly. Since this is done by the firmware on behalf
of the host, even if memory is paged out or cached, the host will
retrieve the memory as the firmware sees it (paged out memory will get
paged in).
Export this mechanism via a debugfs entry for both read and write
access.
WARNING: This mechanism has no protections at all. Invalid addresses may
crash or hang the firmware. Writing to arbitrary memory also comes with
no guarantees.
