mainline inclusion from mainline-v6.0-rc4 commit dfea275e06c26690b1ef27399fd84ce50372b85c category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5QIIF CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
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.
