[ Upstream commit ecce70cf17d91c3dd87a0c4ea00b2d1387729701 ] Physical ib_device does not have an underlying net_device, thus its association with IPoIB net_device cannot be retrieved via ops.get_netdev() or ib_device_get_by_netdev(). ksmbd reads physical ib_device port GUID from the lower 16 bytes of the hardware addresses on IPoIB net_device and match its underlying ib_device using ib_find_gid() Signed-off-by: Kangjing Huang <huangkangjing@gmail.com> Acked-by: Namjae Jeon <linkinjeon@kernel.org> Reviewed-by: Tom Talpey <tom@talpey.com> Signed-off-by: Steve French <stfrench@microsoft.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
