In the loopback tests, the following call trace occurs.
Call Trace:
__rxe_do_task+0x1a/0x30 [rdma_rxe]

ib_uverbs_handler_UVERBS_METHOD_INVOKE_WRITE+0xb9/0xf0 [ib_uverbs]
ib_uverbs_cmd_verbs+0xb16/0xc30 [ib_uverbs]
The root cause is that the actual RDMA connection is not created in the
loopback tests and the rxe_match_dgid will fail randomly.
To fix this call trace which appear in the loopback tests, skip check of
the dgid.

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.
