GL.iNet GL-MT6000 - AQL and WiFi Latency

Installing and Using OpenWrt Network and Wireless Configuration
28

@phinn I put together the script below to provide an easy way to tweak the aql_txq_limit.

Basic usage:
(First time) Set the file as executable: # chmod +x change-aql.sh

Call the script with one of latency, balanced, bandwidth, or a valid integer value. This will tune the AQL Tx queue limit to the preference (or integer value) specified.

Example: Set 'balanced' Preference 
# ./change-aql.sh balanced
