Guojia Liao adcf738b80 net: hns3: cleanup some print format warning
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.

Only the queue_index field in struct hns3_nic_ring_data is

This patch also removes an unused struct hns_queue declaration.

Greg Kroah-Hartman 11ab11e69d hns3: no need to check return value of debugfs_create functions
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.

If the input length reaches the maximum value of size_t, the reverse is

large length. Therefore, the input length should be checked and the value
should be less than or equal to 1024.

Weihang Li ebaf190877 net: hns3: some variable modification
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.

Weihang Li a63457878b net: hns3: Add handling of MAC tunnel interruption
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.
