Add support to create hash (exact-match) filters based on the value of 'hash' field in ch_filter_specification. Allocate SMT/L2T entries if DMAC-rewrite/SMAC-rewrite is requested. Allocate CLIP entry in case of IPv6 filter. Use cpl_act_open_req[6] to send hash filter create request to hw. Also, the filter tuple is calculated as part of sending this request. Hash-filter reply is processed on getting cpl_act_open_rpl. In case of success, various bits/fields in filter-tcb are set per filter requirement, such as enabling filter hitcnts, and/or various header rewrite operations, such as VLAN-rewrite, NAT or (L3/L4)-rewrite, and SMAC/DMAC-rewrite. In case of failure, clear the filter entry and release any hw resources occupied by it. The patch also moves the functions set_tcb_field, set_tcb_tflag and configure_filter_smac towards beginning of file.

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.
