Work queue which is created with IB_WQ_FLAGS_DELAY_DROP won't cause packet drops when there aren't receive WQEs, but will wait until posting of receive WQEs or for some period of time that the device was configured with. It includes: * Add a new creation flag to enable delay drop functionality in a WQ. * A new capability was introduced - IB_RAW_PACKET_CAP_DELAY_DROP, which is the device's ability to delay packet drops when there aren't receive WQEs.

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.
