The current rdma_netdev handling in ipoib hooks the tx_timeout handler, but prints out a totally useless message that prevents effective debugging especially when multiple transmit queues are being used. Add a tx_timeout rdma_netdev hook and implement the callback in the hfi1 to print additional information. The existing non-helpful message is avoided when the driver has presented a callback.

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.
