When register a RoCE client with hnae3vf device, it needs to judge
the device whether support RoCE vf function. Otherwise, it will
lead to calltrace when RoCE is not support vf function and remove
roce device.
The calltrace as follows:
[ 93.156614] Unable to handle kernel NULL pointer dereference at virtual address 00000015
<SNIP>
[ 93.278784] Call trace:

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
