2021-12-31net: hns3: use struct hclge_desc to replace hclgevf_desc in VF cmdq moduleJie Wang
This patch use new common struct hclge_desc to replace struct hclgevf_desc in VF cmdq module and then delete the old struct hclgevf_desc. Signed-off-by: Jie Wang <wangjie125@huawei.com> Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-12-31net: hns3: create new cmdq hardware description structure hclge_comm_hwJie Wang
Currently PF and VF cmdq APIs use struct hclge(vf)_hw to describe cmdq hardware information needed by hclge(vf)_cmd_send. There are a little differences between its child struct hclge_cmq_ring and hclgevf_cmq_ring. It is redundent to use two sets of structures to support same functions. So this patch creates new set of common cmdq hardware description structures(hclge_comm_hw) to unify PF and VF cmdq functions. The struct hclge_desc is still kept to avoid too many meaningless replacement. These new structures will be used to unify hclge(vf)_hw structures in PF and VF cmdq APIs in next patches.

2021-12-31net: hns3: refactor hns3 makefile to support hns3_common moduleJie Wang
Currently we plan to refactor PF and VF cmdq module. A new file folder hns3_common will be created to store new common APIs used by PF and VF cmdq module. Thus the PF and VF compilation process will both depends on the hns3_common. This may cause parallel building problems if we add a new makefile building unit. So this patch combined the PF and VF makefile scripts to the top level makefile to support the new hns3_common which will be created in the next patch.

Currently, the hns3_remove function firstly uninstall client instance, and then uninstall acceletion engine device. The netdevice is freed in client instance uninstall process, but acceletion engine device uninstall process still use it to trace runtime information. This causes a use after free problem.

2021-12-03net: hns3: fix hns3 driver header file not self-contained issueJie Wang
The hns3 driver header file uses the structure of other files, but does not include corresponding file, which causes a check warning that the header file is not self-contained. Therefore, the required header file is included in the header file, and the structure declaration is added to the header file to avoid cyclic dependency of the header file.
