Subject: [PATCH V2 net-next 00/10] net: hns3: misc updates for -next

This patchset includes some misc updates for the HNS3 ethernet driver.

[patch 1&2] separates two bloated function.
[patch 3-5] removes some redundant code.
[patch 6-7] cleans up some coding style issues.
[patch 8-10] adds some debugging information.

Change log:
V1->V2: removes an unnecessary initialization in [patch 1] which
suggested by David Miller.
modified some print format issue and commit log in [patch 8].

Guojia Liao (4):
net: hns3: remove useless proto_support field in struct hclge_fd_cfg
net: hns3: remove two unused structures in hclge_cmd.h
net: hns3: modify some unsuitable type declaration
net: hns3: add debug information for flow table when failed

Huazhong Tan (2):
net: hns3: remove an unnecessary case 0 in hclge_fd_convert_tuple()
net: hns3: clean up some coding style issue

Jian Shen (2):
net: hns3: split out hclge_fd_check_ether_tuple()
net: hns3: split out hclge_get_fd_rule_info()

Yufeng Mo (2):
net: hns3: add support for dumping MAC reg in debugfs
net: hns3: add trace event support for PF/VF mailbox

Subject: [PATCH V2 net-next 04/10] net: hns3: remove useless proto_support field in struct hclge_fd_cfg

From: Guojia Liao <[email protected]>

proto_support field in struct hclge_fd_cfg shows what protocols
in flow direct table are supported now. It is unnecessary since
checking which one is unsupported will be more efficient,
so this patch removes it.

Subject: [PATCH V2 net-next 06/10] net: hns3: modify some unsuitable type declaration

From: Guojia Liao <[email protected]>

In hclge_set_fd_key_config(), parameter 'stage' should be
as enum HCLGE_FD_STAGE, and in hclge_config_key(), 'tuple_size'
should be type u8, also simplify unsigned int with u32 for 'i'.
