Subash Abhinov Kasiviswanathan says: ==================== net: qualcomm: rmnet: Enable csum offloads This series introduces the MAPv4 packet format for checksum offload plus some other minor changes. Patches 1-3 are cleanups. Patch 4 renames the ingress format to data format so that all data formats can be configured using this going forward. Patch 5 uses the pacing helper to improve TCP transmit performance. Patch 6-9 defines the the MAPv4 for checksum offload for RX and TX. A new header and trailer format are used as part of MAPv4. For RX checksum offload, only the 1's complement of the IP payload portion is computed by hardware. The meta data from RX header is used to verify the checksum field in the packet. Note that the IP packet and its field itself is not modified by hardware. This gives metadata to help with the RX checksum. For TX, the required metadata is filled up so hardware can compute the checksum. Patch 10 enables GSO on rmnet devices v1->v2: Fix sparse errors reported by kbuild test robot v2->v3: Update the commit message for Patch 5 based on Eric's comments ==================== Signed-off-by: David S.

README
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.
