[PATCH V2 net-next 2/8] net: hns3: use hns3_get_ae_dev() helper to reduce the unnecessary middle layer conversion

[Jijie Shao]

There are too many indirection layers in the HNS3 driver code.
This issue was previously discussed with the maintainer,
who suggested adding a helper function to fix the issue.
In fact, the hns3_get_ae_dev() helper is already defined
and can fix this issue.

This patch uses hns3_get_ae_dev() helper to reduce the unnecessary
middle layer conversion. Apply it to the whole HNS3 driver.
The former discusstion can be checked from the link.

[PATCH V2 net-next 3/8] net: hns3: use hns3_get_ops() helper to reduce the unnecessary middle layer conversion

[Jijie Shao]

There are too many indirection layers in the HNS3 driver code,
This issue was previously discussed with the maintainer,
who suggested adding a helper function to fix the issue.
In fact, the hns3_get_ops() helper is already defined
and can fix this issue.

This patch uses hns3_get_ops() helper to reduce the unnecessary
middle layer conversion. Apply it to the whole HNS3 driver.
The former discusstion can be checked from the link.

[PATCH V2 net-next 8/8] net: hns3: clear hns alarm: comparison of integer expressions of different signedness

[Jijie Shao]

From: Peiyang Wang <wangpeiyang1@huawei.com>

A static alarm exists in the hns and needs to be cleared.

The alarm is comparison of integer expressions of different
signedness including 's64' and 'long unsigned int',
'int' and 'long unsigned int', 'u32' and 'int',
'int' and 'unsigned int'.

I am sceptical about the merit of setting local variables to NULL like this.
In general defensive coding is not the preferred approach in the Kernel.

And in this case, won't this result in a NULL dereference when
skb_get(skb) is called if the loop this code resides in iterates again?

Can the type of next_to_use be changed to an unsigned type?
It would be nice to avoid casts.

Since HNS3_NIC_LB_TEST_PKT_NUM is 1, the loop will only iterate once,
so the current change will not cause any issues.
However, upon reviewing the code, this change is indeed unnecessary and may cause confusion,
so I will drop this change in the v3.

But I hope this patch can still be retained, and the other changes should be appropriate.

Thansk,

Sorry, the last reply was not cc to netdev...

Some internal tools, and then there are the compiler options, such as -Wsign-compare.

Today I plan to modify the next_to_use type,
but I found that if next_to_use is changed to u32,
it will cause many other places to need to synchronously change the variable type.
At a glance, there are dozens of places.

Therefore, I am considering whether this part can remain unchanged.

Thanks

Thanks for checking.

Based on the above I'd say it can remain unchanged.
It improves things. And leaves room for further improvements later.
