This is meant to ease debugging when asking for support. Just run the
command "nss_diag" and include in your issues/forum posts.

This script is meant to set various skb_recycler settings. There is a
similar version in QSDK, but it's packaged in the main repo, rather than
an external package like 'qca-nss-drv'. To avoid making too many changes
in the main repo, introduce this script in `qca-nss-drv`.
This script will read the following config:
/etc/config/skb_recycler
```
config skb_recycler 'opt'
option max_skbs '1024'
option max_spare_skbs '256'
option enable '1'
```
Users are encouraged to experiment disabling `skb_recycler` to see if
memory leaks are still occuring, especially on 512M boards. There are issues
currently where skb_recycler corrupts skbs during times of high traffic, but there
wasn't a way to completely disable it.

Cleaned up formatting and changed the way console messages are printed.
The message will now properly show up in dmesg output with color, and
date formatting rather than a non descriptive message like the following:
Before:
```
/lib/firmware/qca-nss0-retail.bin 33
/lib/firmware/qca-nss1-retail.bin 33
```
After:
```
[Mon Jul 8 07:21:12 2024] hotplug: symlinking /lib/firmware/qca-nss0.bin to /lib/firmware/qca-nss0-retail.bin
[Mon Jul 8 07:21:12 2024] hotplug: symlinking /lib/firmware/qca-nss1.bin to /lib/firmware/qca-nss1-retail.bin

Reworked flawed smp_affinity logic. It was assumed that all 'nss_*' IRQs
needed to be equally balanced across all CPUs. However, what ends up
happening most of the time is messing with scheduling, thrashing, missed
cache and high context switching.
For each core:
1. nss_empty_buf_sos
2. nss_empty_buf_queue
3. nss_queue0
The IRQs should be kept on the same CPU. Doing so allows NSS cores to
properly feed and empty the queues.

allow users to specify specific metric to view, rather than
everything
Available stats objects:

n2h
unaligned
virt_if
wifi_ext_vdev

Usage: nss_stats obj1 obj2 ...

1.) Rather than modify upstream `smp_affinity` script, move changes into
this init script.
Primarily: "xhci-hcd:usb1", "ppdu-end-interrupts-mac1", "ppdu-end-interrupts-mac2"
2.) Move logging into separate function, and better account for NSS core
specific output.
3.) Set the defaults for `enable_rps` and `enable_log` to true ('1').
4.) Change startup to sequence to `94` [after `smp_affinity` (93)]

1.) Moved `set_affinity` function outside of `enable_rps`
2.) Added 2 new functions `bitmask_to_cpus` and `cpus_to_bitmask`
a.) bitmask_to_cpus - Takes a bitmask of CPUs and returns a
list of CPU numbers. (i.e. `bitmask_to_cpus "f"` -> 0,1,2,3)
b.) cpus_to_bitmask - Takes a comma/space or range list of CPUs and returns
a bitmask. (i.e. `cpus_to_bitmask "2,3"` -> c)
3.) Changed logic of `set_affinity` to now use physical CPUs rather than
knowing the bitmask. This should make it more straight forward when
testing changes
4.) Added an UCI option `enable_log` to enable/disable logging output to
`logger`. Default is `1` (on)
5.) Removed unused UCI options `nss_firmware *`
6.) Changed the way UCI options are retrieved to account for missing
options.
7.) Moved '/lib/debug/qca-nss-drv' to '/usr/bin/nss_stats' so it's in
$PATH and has a more intuitive name
Using the previous version, not all nss related interrupts were being balanced across the available CPU cores.
This makes sure they are as well as moving a bit more off cpu0.
To keep fork as closely synced with upstream, move NSS packages back
into repository. Not sure why they were moved out from my original fork.
* nss-firmware
* qca-nss-crypto
* qca-nss-cfi
Removed the following:
* mhz (already available in packages repo)
* qrtr (unecessary, and has been broken for years)
Also moved packages out of `qca` and back into root directory.
