While hclge is going to reset, it will notify its client with HNAE3_DOWN_CLIENT, so this client should get into a resetting status from this moment, other operations from the stack need to be blocked as well. And when the reset is finished, the client will be notified with HNAE3_UP_CLIENT, so this is the end of the resetting status. This patch uses HNS3_NIC_STATE_RESETTING flag to implement that, and adds hns3_nic_resetting() to indicate which operation is not allowed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
