436396f2 - nfp: support IPsec offloading for NFP3800

Wed, 08 Feb 2023 09:10:00 +0000

nfp: support IPsec offloading for NFP3800Add IPsec offloading support for NFP3800. Include dataplane and control plane.Data plane: add IPsec packet process flow in NFP3800datapath (NFDk).Control plane: add an algorithm support distinction flowin xfrm hook function xdo_dev_state_add(), as NFP3800 hasa different set of IPsec algorithm support.This matches existing support for the NFP6000/NFP4000 andtheir NFD3 datapath.In addition, fixup the md_bytes calculation for NFD3 datapathto make sure the two datapahts are keept in sync.Signed-off-by: Huanhuan Wang Reviewed-by: Niklas Söderlund Signed-off-by: Simon Horman Reviewed-by: Leon Romanovsky Link: https://lore.kernel.org/r/20230208091000.4139974-1-simon.horman@corigine.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/netronome/nfp/Makefile

Fri, 04 Mar 2022 10:22:14 +0000

nfp: xsk: add AF_XDP zero-copy Rx and Tx supportThis patch adds zero-copy Rx and Tx support for AF_XDP sockets. It do soby adding a separate NAPI poll function that is attached to a eachchannel when the XSK socket is attached with XDP_SETUP_XSK_POOL, andrestored when the XSK socket is terminated, this is done per channel.Support for XDP_TX is implemented and the XDP buffer can safely be movedfrom the Rx to the Tx queue and correctly freed and returned to the XSKpool once it's transmitted.Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASSwill allocate a new buffer and copy the zero-copy frame priorpassing it to the kernel stack.This patch is based on previous work by Jakub Kicinski.Signed-off-by: Niklas Söderlund Signed-off-by: Simon Horman Signed-off-by: David S.

Sync these groups withHW via a delayed workqueue to prevent excessive re-configuration. When theworkqueue is triggered it may generate multiple control messages fordifferent groups. These messages are linked via a batch ID and flags toindicate a new batch and the end of a batch.Update private data in each repr to track their LAG lower state flags. Thestate of a repr is used to determine the active netdevs that can beoffloaded. For example, in active-backup mode, we only offload the netdevcurrently active.Signed-off-by: John Hurley Reviewed-by: Pieter Jansen van Vuuren Reviewed-by: Jakub Kicinski Signed-off-by: David S.

73a0329b - nfp: add TLV capabilities to the BAR

Thu, 18 Jan 2018 02:51:01 +0000

nfp: add TLV capabilities to the BARNFP is entirely programmable, including the PCI data interface.Using a fixed control BAR layout certainly makes implementationseasier, but require careful considerations when space is allocated.Once BAR area is allocated to one feature nothing else can use it.Allocating space statically also requires it to be sized upfront,which leads to either unnecessary limitation or wastage.We currently have a 32bit capability word defined which tells driverswhich application FW features are supported. Most of the bitsare exhausted. The same bits are also reused for enabling specificfeatures. Bulk of capabilities don't have a need for an enable bit,however, leading to confusion and wastage.TLVs seems like a better fit for expressing capabilities of applicationsrunning on programmable hardware.This patch leaves the front of the BAR as is, and declares a TLVcapability start at offset 0x58. Most of the space up to 0x0d90is already allocated, but the used space can be wrapped with RESERVEDTLVs. E.g.:Address Type Length 0x0058 RESERVED 0xe00 /* Wrap basic structures */ 0x0e5c FEATURE_A 0x004 0x0e64 FEATURE_B 0x004 0x0e6c RESERVED 0x990 /* Wrap qeueue stats */ 0x1800 FEATURE_C 0x100Signed-off-by: Jakub Kicinski Reviewed-by: Dirk van der Merwe Signed-off-by: David S.
