category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5QIIF
CVE: NA

----------------------------------------------------------------------

Currently, when function hns3_nic_select_queue() converts dscp to priority,
it calls an indirect callback ae_algo->ops->get_dscp_prio to get priority.

However as function hns3_nic_select_queue() is in fast path, the indirect
call may cause degradation of performance. For optimization, this patch
moves dscp_app_cnt and dscp_prio from struct hclge_tm_info to struct
hnae3_knic_private_info, so they can be used in both hclge and hns3 layers.
