2024-07-12octeontx2-af: fix detection of IP layerMichal Mazur1-2/+6
Checksum and length checks are not enabled for IPv4 header with options and IPv6 with extension headers. To fix this a change in enum npc_kpu_lc_ltype is required which will allow adjustment of LTYPE_MASK to detect all types of IP headers.

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure.

2021-07-25octeontx2-af: Fix PKIND overlap between LBK and LMAC interfacesGeetha sowjanya1-0/+3
Currently PKINDs are not assigned to LBK channels. The default value of LBK_CHX_PKIND (channel to PKIND mapping) register is zero, which is resulting in a overlap of pkind between LBK and CGX LMACs. When KPU1 parser config is modified when PTP timestamping is enabled on the CGX LMAC interface it is impacting traffic on LBK interfaces as well. This patch fixes the issue by reserving the PKIND#0 for LBK devices. CGX mapped PF pkind starts from 1 and also fixes the max pkind available.

2021-06-11octeontx2-af: add support for multicast/promisc packet replication featureNaveen Mamindlapalli1-1/+2
Currently, multicast packet filtering is accomplished by installing MCAM rule that matches all-multicast MAC address and has its NPC_RX_ACTION set to unicast to PF. Similarly promisc feature is achieved by installing MCAM rule that matches all the traffic received by the channel and unicast the packets to PF. This approach only applies to PF and is not scalable across VFs. This patch adds support for PF/VF multicast and promisc feature by reserving NIX_RX_MCE_S entries from the global MCE list allocated during NIX block initialization. The NIX_RX_MCE_S entries create a linked list with a flag indicating the end of the list, and each entry points to a PF_FUNC (either PF or VF). When a packet NPC_RX_ACTION is set to MCAST, the corresponding NIX_RX_MCE_S list is traversed and the packet is queued to each PF_FUNC available on the list. The PF or VF driver adds the multicast/promisc packet match entry and updates the MCE list with correspondng PF_FUNC. When a PF or VF interface is disabled, the corresponding NIX_RX_MCE_S entry is removed from the MCE list and the MCAM entry will be disabled if the list is empty.

The installed MCAM rules are stored in a list that will be traversed later to delete the MCAM entries when the interface is brought down or when PCIe FLR is received. The delete mailbox supports deleting a single MCAM entry or range of entries or all the MCAM entries owned by the pcifunc. Each MCAM entry can be associated with a HW match stat entry if the mailbox requester wants to check the hit count for debugging. Modified adding default unicast DMAC match rule using install flow API. The default unicast DMAC match entry installed by Administrative Function is saved and can be changed later by the mailbox user to fit additional fields, or the default MCAM entry rule action can be used for other flow rules installed later.

2020-09-29octeontx2-af: add parser support for Forward DSAHariprasad Kelam1-0/+1
Marvell Prestera switches supports distributed switch architecture by inserting Forward DSA tag of 4 bytes right after ethernet SMAC. This tag don't have a tpid field. This patch provides parser and extraction support for the same. Default ldata extraction profile added for FDSA such that Src_port is extracted and placed inplace of vlanid field. Like extended DSA and eDSA tags,a special PKIND of 62 is used for this tag. Signed-off-by: Hariprasad Kelam <hkelam@marvell.com> Acked-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.

2020-09-29octeontx2-af: cleanup KPU config dataStanislaw Kardach1-0/+36
Refactor KPU related NPC code gathering all configuration data in a structured format and putting it in one place (npc_profile.h). This increases readability and makes it easier to extend the profile configuration (as opposed to jumping between multiple header and source files). To do this: * Gather all KPU profile related data into a single adapter struct. * Convert the built-in MKEX definition to a structured one to streamline the MKEX loading. * Convert LT default register configuration into a structure, keeping default protocol settings in same file where identifiers for those protocols are defined. * Add a single point for KPU profile loading, so that its source may change in the future once proper interfaces for loading such config are in place.

2020-09-29octeontx2-af: fix LD CUSTOM LTYPE aliasingStanislaw Kardach1-2/+2
Since LD contains LTYPE definitions tweaked toward efficient NIX_AF_RX_FLOW_KEY_ALG(0..31)_FIELD(0..4) usage, the original location of NPC_LT_LD_CUSTOM0/1 was aliased with MPLS_IN_* definitions. Moving custom frame to value 6 and 7 removes the aliasing at the cost of custom frames being also considered when TCP/UDP RSS algo is configured. However since the goal of CUSTOM frames is to classify them to a separate set of RQs, this cost is acceptable.

2019-11-15octeontx2-af: Update NPC KPU packet parsing profileHao Zheng1-29/+66
Updated NPC KPU packet parsing profile with support for following - Fragmentation support for IPv4 IPv6 outer header - NIX instruction header support - QinQ with TPID of 0x8100 as non inner most vlan tag, as legacy network equipments still generate QinQ packets with this configuration. - To better support RSS for tunnelled packets, udp based tunnel protocols such as vxlan, vxlan-gpe, geneve and gtpu are now captured into a separate layer E. Consequently, the inner packet headers are pushed one layer down to LF, LG, and LH accordingly. - Support for rfc7510 mpls in udp. Up to 4 MPLS labels can be parsed and captured in one layer LE. - Parser support for DSA, extended DSA and eDSA tags right after ethernet header by Marvell SOHO and Falcon switches. For extended DSA and eDSA tags, a special PKIND of 62 is used, as these tags don't contain a tpid field. - Higig2 protocol header parsing support, added a NPC_LT_LA_HIGIG2_ETHER for a combined header of HIGIG2 and Ethernet. Add a NPC_LT_LA_IH_NIX_HIGIG2_ETHER for a combined header of nix_ih, HIGIG2 and Ethernet on egress side. Also added 2 upper flags in LA to indicate the presence of nix_ih and HIGIG2. Other changes include - IPv4.TTL==0 IPv6.HLIM==0 check - Per RFC 1858, mark fragment offset == 1 as error - TCP invalid flags check - Separate error codes for outer and inner IPv4 checksum errors. - Fix a parser error when KPU parses incoming IPSec ESP and AH packets - NPC vtag capture/strip hardware expect tag pointer to point to tpid/ethertype instead of tci. So move lb_ptr to point to tpid/ethertype. - Fix npc parser error when parsing udp packets that don't have any payload. - For a single MCAM entry to match on packets with one or stacked vlan tags combine NPC_LT_LB_STAG and NPC_LT_LB_QINQ to NPC_LT_LB_STAG_QINQ. - NVGRE to have a separate ltype LD_NVGRE instead of combined with LD_GRE. - Reserve top LD/LTYPEs to support custom KPU profile fields.

2018-12-04octeontx2-af: Enable mkex profileVamsi Attunuru1-0/+18
The following set of NPC registers allow the driver to configure NPC to generate different key value schemes to compare against packet payload in MCAM search. NPC_AF_INTF(0..1)_KEX_CFG NPC_AF_KEX_LDATA(0..1)_FLAGS_CFG NPC_AF_INTF(0..1)_LID(0..7)_LT(0..15)_LD(0..1)_CFG NPC_AF_INTF(0..1)_LDATA(0..1)_FLAGS(0..15)_CFG Currently, the AF driver populates these registers to configure the default values to address the most common use cases such as key generation for channel number + DMAC. The secure firmware stores different configuration value of these registers to enable different NPC use case along with the name for the lookup. Patch loads profile binary from secure firmware over the exiting CGX mailbox interface and apply the profile. AF driver shall fall back to the default configuration in case of any errors. The AF consumer driver can know the selected profile on response to NPC_GET_KEX_CFG mailbox by introducing mkex_pfl_name in the struct npc_get_kex_cfg_rsp.

2018-11-20octeontx2-af: Add support for stripping STAG/CTAGTomasz Duszynski1-0/+6
This works by shadowing existing UCAST MCAM entry with a new one additionally matching either NPC_LT_LB_CTAG or NPC_LT_LB_STAG. For this to fully work one needs to send properly configured NIX_VTAG_CFG message afterwards i.e with strip and capture enabled and type set to 0. On receiving tagged packet NIX will remove outer VLAN and capture TCI in NIX_RX_PARSE_S. Also simplified RX Vtag configuration flow With this setting STRIP/CAPTURE VTAG actions separately would be possible. Following combinations are possible: STRIP, STRIP and CAPTURE, CAPTURE or nothing (0 disables respective actions).

2018-10-23octeontx2-af: Add NPC KPU profileHao Zheng1-0/+143
NPC block is responsible for parsing and forwarding packets to different NIXLFs. NPC has 16 KPU engines (Kangaroo parse engine) and one iKPU which represents pkinds. Each physical port either CGX/LBK is assigned a pkind and upon receiving a packet HW takes that port's pkind and starts parsing as per the KPU engines config. This patch adds header files which contain configuration profile/array for each of the iKPU and 16 KPU engines.
