The discussion on netdev suggests using BQL, but at speed levels below 10mbit
two packets of buffering is enough.

Hi Dave,

thanks for your notes.

How do you come to the amount of two packets (MTU * 2 < QCA7000 internal buffer )?
Do you mean tx ring of the driver with your suggestion?
Is the default netdev tx queue length of 100 okay?
