Configuring SQM to reduce Bufferbloat

Hi @mmonaghan, I am continuing the investigation in SQM package installation bricks GL-MT1300 (Beryl) firmware 3.200 since it seems a GL-MT1300 issue in particular.

My Beryl is back after Debrick and while we figure things out for SQM, which is a really desirable feature IMHO, I am experimenting with Hardware flow offloading since I will have to disable it once that works :grin:
