2019-10-31net: hns3: cleanup byte order issues when printedGuojia Liao
Though the hip08 and the IMP(Intelligent Management Processor) have the same byte order right now, it is better to convert __be or __le variable into the CPU's byte order before print.

2019-10-31net: hns3: cleanup some print format warningGuojia Liao
Using '%d' for printing type unsigned int or '%u' for type int would cause static tools to give false warnings, so this patch cleanups this warning by using the suitable format specifier of the type of variable. BTW, modifies the type of some variables and macro to synchronize with their usage.

2019-10-21net: hns3: remove struct hns3_nic_ring_data in hns3_enet moduleYunsheng Lin
Only the queue_index field in struct hns3_nic_ring_data is used, other field is unused and unnecessary for hns3 driver, so this patch removes it and move the queue_index field to hns3_enet_ring. This patch also removes an unused struct hns_queue declaration. Signed-off-by: Yunsheng Lin <linyunsheng@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2019-08-10hns3: no need to check return value of debugfs_create functionsGreg Kroah-Hartman
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

2019-08-09net: hns3: add input length check for debugfs write functionYufeng Mo
If the input length reaches the maximum value of size_t, the reverse is triggered when 1 is added. In addition, there is no need to have such a large length. Therefore, the input length should be checked and the value should be less than or equal to 1024.

2019-06-14net: hns3: some variable modificationWeihang Li
This patch does following things: 1. add the keyword const before some variables which won't be modified in functions. 2. changes some variables from signed to unsigned to avoid bitwise operation on signed variables. 3. adds or removes initialization of some variables. 4. defines a new structure to help parsing mailbox messages instead of using an array which is harder to get the meaning of each element.

2019-04-19net: hns3: Add handling of MAC tunnel interruptionWeihang Li
MAC tnl interruptions are different from other type of RAS and MSI-X errors, because some bits, such as OVF/LR/RF will occur during link up and down. The drivers should clear status of all MAC tnl interruption bits but shouldn't print any message that would mislead the users. In case that link down and re-up in a short time because of some reasons, we record when they occurred, and users can query them by debugfs.
