This patch adds the functions to receive TID RDMA READ response. The TID resource information in the KDETH packet header will direct the hardware to deliver the packet payload to the user buffer automatically and the software will handle the packet header for the last packet of a segment as all other packet headers are suppressed by default. The TID entries will be freed when all packets for a segment have been received. This patch also adds the functions to handle KDETH eflag errors, including flow sequence and generation errors, when a TID RDMA READ response packet is received . The flow sequence error can be recovered by software checking of the flow sequence and will disappear when the hardware flow is programmed with a new generation number.

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.
