Bug Fixes

3678881

Description: Performance issues are observed due to context switches over the hardware priority buffers that caused slower packet being send when sending traffic with many different VLAN (CoS PCP/801.2p) priorities.

To fix the issue, the driver provides a new module parameter trust_dscp_same_priority to map all DSCP priorities to the same traffic class to avoid such behavior.
