[Cake] fq_codel on 3g network in Mauritius

You could also use a custom kernel that would allow you to add
fq_codel/cake then add custom rules to it.

I would advise a setup such as: AFWall to run scripts depending on whether
it's WiFi or Mobile (3G/4G). The script would be a simplified debloat.sh
just adding simple tc fq_codel/cake commands.

I tried this before on the Samsung Galaxy Nexus back on 2013 [1] [2] with
AK_Kernel. I had interesting results though mixed ones. It was mostly due
to mobile data quality being awfully varied. Therefore, I wasn't
knowledgeable to find a good script setup that catered for all the moving
parts. Nonetheless, it improved my situation. I recommend it.

I've been meaning to try this again using a modified Franco kernel [2] for
Huawei Nexus 6P. However, as with everyone else, Real Life(TM) has a
tendency to get in the way. :) I don't use custom ROMs. It would be a stock
Nexus ROM installation, SU root for scripts/tc and custom kernel for
fq_codel/cake kernels.

We could try if people are interested. However, I can only be of help after
