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.
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 of dumping MAC reg in debugfs
net: hns3: add trace event support for PF/VF mailbox

Since case default has included case 0, so removes this
redundant case 0.

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.

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'.
