[dpdk-dev] [PATCH 0/4] bugfix for hns3 PMD

[Min Hu (Connor)]

This patchset contains four bugfixes for hns3 PMD.

Chengwen Feng (4):

[dpdk-dev] [PATCH 1/4] net/hns3: fix error mbx messages prompt errors

[Min Hu (Connor)]

From: Chengwen Feng <fengchengwen@huawei.com>

The hns3_dev_handle_mbx_msg() could be called under both PF and VF,
but the error messages show VF.

[dpdk-dev] [PATCH 2/4] net/hns3: fix PF miss link status notify message

[Min Hu (Connor)]

From: Chengwen Feng <fengchengwen@huawei.com>

The opcode of the link status notification message reported by the
firmware is zero, it will be filtered out because driver treats it as
already processed message. As a result, the PF can't update the link
status in a timely manner.

Because only VF can set opcode to zero when process mailbox message,
so we add a judgment to make sure the PF messages will not filter out.

Why not s/struct hns3_mbx_pf_to_vf_cmd/struct hns3_mbx_vf_to_pf_cmd/ but change
to parameter to "void *", wouldn't it reduce the type check?

Only this message needs to be converted using hns3_mbx_vf_to_pf_cmd.
All other messages are processed using hns3_mbx_pf_to_vf_cmd.
So here we simplifying fix it.

Beside we will refactor hns3_mbx module in later version because the
PF and VF process logic is mixed.

There is a single caller of the function, which send parameter as "struct
hns3_mbx_pf_to_vf_cmd *req", so what is the point of making the parameter as
"void *" and inside the function cast it to "struct hns3_mbx_vf_to_pf_cmd *req =
data;"?
Instead of defining parameter as "struct hns3_mbx_pf_to_vf_cmd *req".

Hi Connor,

I guess I am missing something obvious, why not get the parameter as 'struct
hns3_mbx_vf_to_pf_cmd' at first place?

The link fails code should be parsed using the structure
hns3_mbx_vf_to_pf_cmd, else it will parse fail.

I am asking just to double check, the 'msg' type is different of
'hns3_mbx_pf_to_vf_cmd' & 'hns3_mbx_vf_to_pf_cmd', one is 'uint8_t', other is
'uint16_t', and 'msg' is used in the function 'hns3pf_handle_link_change_event()'.
Is the 'msg' usage still correct after this change?

> +			hns3pf_handle_link_change_event(hw,
> +				(struct hns3_mbx_vf_to_pf_cmd *)req);

Will it be more readable if 'desc->data' cast to "struct hns3_mbx_vf_to_pf_cmd
*" (instead of 'req')? Up to you, I can proceed with this one if you prefer.

Hi, it is correct.
Currently, msg from PF or VF are all handled in the same
handler（hns3_dev_handle_mbx_msg）, we do different handling
according to different msg.
In futrue, we will separate handler from PF and VF.

Let me clarify what I mean, 'msg' is accessed with an index like
"req->msg[LINK_FAIL_CODE_OFFSET]", and the 'req->msg' type is different as you
change the 'req' type. It changes 'uint8_t' -> 'uint16_t', which makes
"req->msg[LINK_FAIL_CODE_OFFSET]" point completely different location, can you
please confirm this is expected/correct?
