Currently there is no limit to the number of VFs netdevsim can enable. In a real systems this value exist and used by the driver. Fore example, some features might need to consider this value when allocating memory. Expose max_vfs variable to debugfs as configurable resource. If are VFs configured (num_vfs != 0) then changing of max_vfs not allowed. Co-developed-by:

Simon Horman says: ==================== Introduce conntrack offloading to the nfp driver Louis Peens says: This is the first in a series of patches to offload conntrack to the nfp. The approach followed is to flatten out three different flow rules into a single offloaded flow. The three different flows are: 1) The rule sending the packet to conntrack (pre_ct) 2) The rule matching on +trk+est after a packet has been through conntrack. (post_ct) 3) The rule received via callback from the netfilter (nft) In order to offload a flow we need a combination of all three flows, but they could be added/deleted at different times and in different order. To solve this we save potential offloadable CT flows in the driver, and every time we receive a callback we check against these saved flows for valid merges. Once we have a valid combination of all three flows this will be offloaded to the NFP. This is demonstrated in the diagram below. +-------------+ +----------+ | pre_ct flow +--------+ | nft flow | +-------------+ v +------+---+ +----------+ | | tc_merge +--------+ | +----------+ v v +--------------+ ^ +-------------+ | post_ct flow +-------+ +---+nft_tc merge | +--------------+ | +-------------+ | | | v Offload to nfp This series is only up to the point of the pre_ct and post_ct merges into the tc_merge. Follow up series will continue to add the nft flows and merging of these flows with the result of the pre_ct and post_ct merged flows. Changes since v2: - nfp: flower-ct: add zone table entry when handling pre/post_ct flows Fixed another docstring. Should finally have the patch check environment properly configured now to avoid more of these. - nfp: flower-ct: add tc merge functionality Fixed warning found by "kernel test robot <lkp@intel.com>" Added code comment explaining chain_index comparison Changes since v1: - nfp: flower-ct: add ct zone table Fixed unused variable compile warning Fixed missing colon in struct description ==================== Acked-by:Jakub Kicinski <kuba@kernel.org> Signed-off-by:

Add merging of pre/post_ct flow rules into the tc_merge table. Pre_ct flows needs to be merge with post_ct flows and vice versa. This needs to be done for all flows in the same zone table, as well as with the wc_zone_table, which is for flows masking out ct_zone info. Cleanup is happening when all the tables are cleared up and prints a warning traceback as this is not expected in the final version. At this point we are not actually returning success for the offload, so we do not get any delete requests for flows, so we can't delete them that way yet. This means that cleanup happens in what would usually be an exception path. Signed-off-by:

Sharath Chandra Vurukala says: ==================== net: qualcomm: rmnet: Enable Mapv5 This series introduces the MAPv5 packet format. Patch 0 documents the MAPv4/v5. Patch 1 introduces the MAPv5 and the Inline checksum offload for RX/Ingress. Patch 2 introduces the MAPv5 and the Inline checksum offload for TX/Egress. A new checksum header format is used as part of MAPv5.For RX checksum offload, the checksum is verified by the HW and the validity is marked in the checksum header of MAPv5. For TX, the required metadata is filled up so hardware can compute the checksum. v1->v2: - Fixed the compilation errors, warnings reported by kernel test robot. - Checksum header definition is expanded to support big, little endian formats as mentioned by Jakub. v2->v3: - Fixed compilation errors reported by kernel bot for big endian flavor. v3->v4: - Made changes to use masks instead of C bit-fields as suggested by Jakub/Alex. v4->v5: - Corrected checkpatch errors and warnings reported by patchwork. v5->v6: - Corrected the bug identified by Alex and incorporated all his comments. v6->v7: - Removed duplicate inclusion of linux/bitfield.h in rmnet_map_data.c v7->v8: - Have addressed comments given by JAkub on v7 patches. - As suggested by Jakub, skb_cow_head() is used instead of expanding the head directly. This is now done in rmnet_map_egress_handler(). ==================== Signed-off-by: -

Adding support for MAPv5 egress packets. This involves adding the MAPv5 header and setting the csum_valid_required in the checksum header to request HW compute the checksum. Corresponding stats are incremented based on whether the checksum is computed in software or HW. New stat has been added which represents the count of packets whose checksum is calculated by the HW.

Adding support for processing of MAPv5 downlink packets. It involves parsing the Mapv5 packet and checking the csum header to know whether the hardware has validated the checksum and is valid or not. Based on the checksum valid bit the corresponding stats are incremented and skb->ip_summed is marked either CHECKSUM_UNNECESSARY or left as CHEKSUM_NONE to let network stack revalidate the checksum and update the respective snmp stats. Current MAPV1 header has been modified, the reserved field in the Mapv1 header is now used for next header indication. Signed-off-by:

Tony Nguyen says: ==================== iwl-next Intel Wired LAN Driver Updates 2021-06-01 This pull request is targeting net-next and rdma-next branches. These patches have been reviewed by netdev and rdma mailing lists[1]. This series adds RDMA support to the ice driver for E810 devices and converts the i40e driver to use the auxiliary bus infrastructure for X722 devices. The PCI netdev drivers register auxiliary RDMA devices that will bind to auxiliary drivers registered by the new irdma module.
