Add a new optional conntrack action attribute OVS_CT_ATTR_EVENTMASK, which can be used in conjunction with the commit flag (OVS_CT_ATTR_COMMIT) to set the mask of bits specifying which conntrack events (IPCT_*) should be delivered via the Netfilter netlink multicast groups. Default behavior depends on the system configuration, but typically a lot of events are delivered. This can be very chatty for the NFNLGRP_CONNTRACK_UPDATE group, even if only some types of events are of interest. Netfilter core init_conntrack() adds the event cache extension, so we only need to set the ctmask value. However, if the system is configured without support for events, the setting will be skipped due to extension not being found.

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.
