Rahul Lakkireddy says: ==================== cxgb4: add support to offload tc flower This series of patches add support to offload tc flower onto Chelsio NICs. Patch 1 adds basic skeleton to prepare for offloading tc flower flows. Patch 2 adds support to add/remove flows for offload. Flows can have accompanying masks. Following match and action are currently supported for offload: Match: ether-protocol, IPv4/IPv6 addresses, L4 ports (TCP/UDP) Action: drop, redirect to another port on the device. Patch 3 adds support to offload tc-flower flows having vlan actions: pop, push, and modify. Patch 4 adds support to fetch stats for the offloaded tc flower flows from hardware. Support for offloading more match and action types are to be followed in subsequent series. v2: - Setting ftid to -1 not required after bitmap_find_free_region in cxgb4_get_free_ftid. - Direct return can be used as jumping to error path is not needed if flower entry allocation failed in cxgb4_tc_flower_replace. Same applies if flower entry not found in cxgb4_tc_flower_destroy. - Also, removed an extra return from cxgb4_tc_flower_destroy. - Avoid wrapping line for netdev_err message. Also, use consistent error message string. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
