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.

Yufeng Mo 97afd47b36 net: hns3: add function type check for debugfs help information 
PF supports all debugfs command, but VF only supports part of
debugfs command. So VF should not show unsupported help information.

This patch adds a check for PF and PF to show the supportable help
information.

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.
