From 71a963cfc50b0309ca3192c7258569e0d5477ab0 Mon Sep 17 00:00:00 2001 From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com> Date: Fri, 7 Dec 2018 14:00:15 +0000 Subject: [PATCH] net: aquantia: increase max number of hw queues 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.
