Replace pfifo/default-small queue types with fq-codel or CAKE so ping stays flat when bandwidth is full.

Bufferbloat happens when packets pile up in the queue while a customer's bandwidth is full. fq-codel and CAKE separate small flows (games, chat) from big downloads and keep the queue short.

• A queue type only works when a limit is reached: put it on queues/profiles that have a max-limit or rate-limit.
• Turn off FastTrack for customer traffic, since FastTrack traffic skips queues.

How to use: Copy the script, open Winbox → New Terminal, paste. Or Download .rsc, upload it in Files, then run /import file-name=anti-bufferbloat.rsc.
