ACK packets are generally associated with request completion and resource release and therefore should be sent first. This patch optimizes the send engine by using the following policies: (1) QPs with RVT_S_ACK_PENDING bit set in qp->s_flags or qpriv->s_flags should have their priority incremented; (2) QPs with ACK or TID-ACK packet queued should have their priority incremented; (3) When a QP is queued to the wait list due to resource constraints, it will be queued to the head if it has ACK packet to send; (4) When selecting qps to run from the wait list, the one with the highest priority and starve_cnt will be selected; each priority will be equivalent to a fixed number of starve_cnt (16).

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.
