During heavy tx traffic, control messages (sent by liquidio driver to NIC firmware) sometimes do not get processed in a timely manner. Reason is: the low-level metadata of control messages and that of egress network packets indicate that they have the same priority. Fix it by setting a higher priority for control messages through the new ctrl_qpg field in the oct_txpciq struct. It is the NIC firmware that does the actual setting of priority by writing to the new ctrl_qpg field; the host driver treats that value as opaque and just assigns it to pki_ih3->qpg Signed-off-by: Intiyaz Basha <intiyaz.basha@cavium.com> Signed-off-by: Felix Manlunas <felix.manlunas@cavium.com> Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
