[dpdk-dev] [PATCH v2 43/52] net/ice/base: adjust scheduler default BW weight

Qi Zhang qi.z.zhang at intel.com
Tue Jun 9 13:59:52 CEST 2020


By default the queues are configured in legacy mode. The default
BW settings for legacy/advanced modes are different. The existing
code was using the advanced mode default value of 1 which was
incorrect. This caused the unbalanced BW sharing among siblings.
The recommneded default value is applied.
