During removing the driver, we needs to notify the roce engine to stop working immediately,and symmetrically recycle the hardware resources requested during initialization. The hardware provides a command called function clear that can package these operations,so that the driver can only focus on releasing resources that applied from the operating system. This patch implements the call of this command. Signed-off-by: Lang Cheng <chenglang@huawei.com> Signed-off-by: Lijun Ou <oulijun@huawei.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
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.
