net: aquantia: increase max number of hw queues

logost · davem330 · commit 71a963cfc50b · 2018-12-07T12:49:09.000-08:00
Increase the upper limit of the hw queues up to 8.
This makes RSS better on multiheaded cpus.

This is a maximum AQC hardware supports in one traffic class.

The actual value is still limited by a number of available cpu cores.
