2023-08-02T09:09:32+00:00

This patch enables offload for TC classifier flower rules which matches against SPI field. Signed-off-by: Ratheesh Kannoth Signed-off-by: David S. Miller

net: flow_offload: add support for ARP frame matching

2022-11-14T11:24:16+00:00

This adds a new flow_rule_match_arp function that allows drivers to be able to dissect ARP frames. Signed-off-by: Steen Hegelund Signed-off-by: David S. Miller

flow_offload: Introduce flow_match_l2tpv3

2022-09-20T07:13:38+00:00

Allow to offload L2TPv3 filters by adding flow_rule_match_l2tpv3. Drivers can extract L2TPv3 specific fields from now on. Signed-off-by: Wojciech Drewek Signed-off-by: Tony Nguyen Signed-off-by: Paolo Abeni

flow_offload: Introduce flow_match_pppoe

netfilter: nf_tables: bail out early if hardware offload is not supported

2022-06-06T17:19:15+00:00

If user requests for NFT_CHAIN_HW_OFFLOAD, then check if either device provides the .ndo_setup_tc interface or there is an indirect flow block that has been registered. Otherwise, bail out early from the preparation phase. Moreover, validate that family == NFPROTO_NETDEV and hook is NF_NETDEV_INGRESS.

flow_offload: add reoffload process to update hw_count

2021-12-19T14:08:48+00:00

Add reoffload process to update hw_count when driver is inserted or removed. We will delete the action if it is with skip_sw flag and not offloaded to any hardware in reoffload process. When reoffloading actions, we still offload the actions that are added independent of filters.

flow_offload: allow user to offload tc action to net device

2021-12-19T14:08:48+00:00

Use flow_indr_dev_register/flow_indr_dev_setup_offload to offload tc action. We need to call tc_cleanup_flow_action to clean up tc action entry since in tc_setup_action, some actions may hold dev refcnt, especially the mirror action.

net: Fix offloading indirect devices dependency on qdisc order creation

2021-08-19T12:19:30+00:00

Currently, when creating an ingress qdisc on an indirect device before the driver registered for callbacks, the driver will not have a chance to register its filter configuration callbacks. To fix that, modify the code such that it keeps track of all the ingress qdiscs that call flow_indr_dev_setup_offload(). When a driver calls flow_indr_dev_register(), go through the list of tracked ingress qdiscs and call the driver callback entry point so as to give it a chance to register its callback.
