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.
