Currently, the driver sets handshake status to tell the hardware
that the driver have downed the netdev and it can continue with
reset process. The driver will clear the handshake status when
re-initializing the CMDQ, and does not recover this status
when reset fail, which may cause the hardware to wait for
the handshake status to be set and not being able to continue
with reset process.
So this patch delays clearing handshake status just before UP,
and recovers this status when reset fail.
BTW, this patch adds a new function hclge(vf)_reset_handshake() to
deal with the reset handshake issue, and renames
HCLGE(VF)_NIC_CMQ_ENABLE to HCLGE(VF)_NIC_SW_RST_RDY which
represents this register bit more accurately.

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.
