From: Tomasz Duszynski 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

[PATCH v3 18/21] octeontx2-af: Configure AF VFs to talk over LBK channels

From: Tomasz Duszynski Configure AF VFs such that they are able to talk over consecutive loopback channels. If 8 VFs are attached to AF then communication will work as below: TX RX lbk0 -> lbk1 lbk1 -> lbk0 lbk2 -> lbk3 lbk3 -> lbk2 lbk4 -> lbk5 lbk5 -> lbk4 lbk6 -> lbk7 lbk7 -> lbk6

[PATCH v3 17/21] octeontx2-af: Enable sriov on AF to create VFs

From: Tomasz Duszynski Enable all AF VFs during probe. Since AF's VFs work in pairs (eg: Pkts sent on VF0 are received by VF1 and viceversa), enable only even number of VFs out of totalVFs, which should again be less than number of loopback (LBK) channels. Also enable VF's mailbox interrupts.

[PATCH v3 14/21] octeontx2-af: Add FLR interrupt handler

From: Geetha sowjanya RVU admin function (AF) has all the priviliges to cleanup HW state when VFIO triggers a PCIe function level reset (FLR) due to either reset or a VM crash. FLR for RVU PF1-PFn will trigger an IRQ to AF. This patch enables all RVU PF's FLR interrupts and registers a handler.

[PATCH v2 12/17] octeontx2-af: Add LMAC channel info to NIXLF_ALLOC response

From: Stanislaw Kardach Add LMAC channel info like Rx/Tx channel base and count to NIXLF_ALLOC mailbox message response. This info is used by NIXLF attached RVU PF/VF to configure SQ's default channel, TL3_TL2_LINKX_CFG and to install MCAM rules in NPC based on matching ingress channel number.

[PATCH v2 13/17] octeontx2-af: Install ucast and bcast pkt forwarding rules

From: Sunil Goutham Upon NIXLF_ALLOC install a unicast forwarding rule in NPC MCAM like below - Match pkt DMAC with NIXLF attached PF/VF's MAC address. - Ingress channel - Action is UCAST - Forward to PF_FUNC of this NIXLF And broadcast pkt forwarding rule as - Match L2B bit in MCAM search

[PATCH v2 11/17] octeontx2-af: NPC MCAM and LDATA extract minimal configuration

From: Sunil Goutham This patch adds some minimal configuration for NPC MCAM and LDATA extraction which is sufficient enough to install ucast/bcast/promiscuous forwarding rules. Below is the config done - LDATA extraction config to extract DMAC from pkt to offset 64bit in MCAM search key. - Set

[PATCH v2 14/17] octeontx2-af: NIX Rx flowkey configuration for RSS

From: Sunil Goutham Configure NIX RX flowkey algorithm configuration to support RSS (receive side scaling). Currently support for only L3/L4 2-tuple and 4-tuple hash of IPv4/v6/TCP/UDP/SCTP is added. HW supports upto 32 different flowkey algorithms which SW can define, this patch defines 9. NPC

[PATCH v2 15/17] octeontx2-af: Support for changing RSS algorithm

From: Sunil Goutham This patch adds support for a RVU PF/VF to change NIX Rx flowkey algorithm index in NPC RX RSS_ACTION. eg: a ethtool command changing RSS algorithm for a netdev interface would trigger this change in NPC. If PF/VF doesn't specify any MCAM entry index then default UCAST entry

[PATCH v2 16/17] octeontx2-af: Support for setting MAC address

From: Sunil Goutham Added a new mailbox message for a PF/VF to set/update it's NIXLF's MAC address. Also updates unicast NPC MCAM entry with this address as matching DMAC. Signed-off-by: Sunil Goutham --- drivers/net/ethernet/marvell/octeontx2/af/mbox.h | 8 ++-

[PATCH v2 17/17] octeontx2-af: Support for NIXLF's UCAST/PROMISC/ALLMULTI modes

From: Sunil Goutham By default NIXLF is set in UCAST mode. This patch adds a new mailbox message which when sent by a RVU PF changes this default mode. When promiscuous mode is needed, the reserved promisc entry for each of RVU PF is setup to match against ingress channel number only, so that

[PATCH v2 02/17] octeontx2-af: NIX Tx scheduler queue config support

From: Sunil Goutham This patch adds support for a PF/VF driver to configure NIX transmit scheduler queues via mbox. Since PF/VF doesn't know the absolute HW index of the NIXLF attached to it, AF traps the register config and overwrites with the correct NIXLF index. HW supports shaping,

[PATCH v2 01/17] octeontx2-af: NIX Tx scheduler queues alloc/free

From: Sunil Goutham Added support for a PF/VF to allocate or free NIX transmit scheduler queues via mbox. For setting up pkt transmission priorities between queues, the scheduler queues have to be contiguous w.r.t their HW indices. So both contiguous and non-contiguous allocations are supported.

[PATCH v2 05/17] octeontx2-af: Config NPC KPU engines with parser profile

From: Sunil Goutham This patch configures all 16 KPUs and iKPU (pkinds) with the KPU parser profile defined in npc_profile.h. Each KPU engine has a 128 entry CAM, only CAM entries which are listed in the profile are enabled and rest are left disabled. Also - Memory is allocated for pkind's

[PATCH v2 08/17] octeontx2-af: Update bcast list upon NIXLF alloc/free

From: Sunil Goutham Upon NIXLF ALLOC/FREE, add or remove corresponding PF_FUNC from the broadcast packet replication list of the CGX LMAC mapped RVU PF. Signed-off-by: Sunil Goutham --- .../net/ethernet/marvell/octeontx2/af/rvu_nix.c| 133 + 1 file changed, 133

[PATCH v2 09/17] octeontx2-af: Support for VTAG strip and capture

From: Vamsi Attunuru Added support for PF/VF drivers to configure NIX to capture and/or strip VLAN tag from ingress packets. Signed-off-by: Vamsi Attunuru Signed-off-by: Sunil Goutham --- drivers/net/ethernet/marvell/octeontx2/af/mbox.h | 35 -

[PATCH v2 07/17] octeontx2-af: Broadcast packet replication support

From: Sunil Goutham Allocate memory for mcast/bcast/mirror replication entry contexts, replication buffers (used by HW) and config HW with corresponding memory bases. Added support for installing MCEs via NIX AQ mbox. For now support is restricted to broadcast pkt replication, hence MCE table

[PATCH v2 04/17] octeontx2-af: Add NPC KPU profile

From: Hao Zheng 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

[PATCH v2 03/17] octeontx2-af: Reset NIXLF's Rx/Tx stats

From: Vamsi Attunuru This patch adds a new mailbox message to reset a NIXLF's receive and transmit HW stats. Signed-off-by: Vamsi Attunuru Signed-off-by: Sunil Goutham --- drivers/net/ethernet/marvell/octeontx2/af/mbox.h | 3 ++- drivers/net/ethernet/marvell/octeontx2/af/rvu.h| 2 ++

[PATCH v2 06/17] octeontx2-af: Config pkind for CGX mapped PFs

From: Geetha sowjanya For each CGX LMAC that is mapped to a RVU PF, allocate a pkind and config the same in CGX. For a received packet at CGX LMAC interface this pkind is used by NPC block to start parsing of packet. Signed-off-by: Geetha sowjanya Signed-off-by: Sunil Goutham ---

[PATCH v2 10/17] octeontx2-af: Enable packet length and csum validation

From: Sunil Goutham Config NPC layer info from KPU profile into protocol checker to identify outer L2/IPv4/TCP/UDP headers in a packet. And enable IPv4 checksum validation. L3/L4 and L4 CSUM validation will be enabled by PF/VF drivers by configuring NIX_AF_LF(0..127)_RX_CFG via mbox i.e

[PATCH v2 00/17] octeontx2-af: NPC parser and NIX blocks initialization

From: Sunil Goutham This patchset is a continuation to earlier submitted two patch series to add a new driver for Marvell's OcteonTX2 SOC's Resource virtualization unit (RVU) admin function driver. 1. octeontx2-af: Add RVU Admin Function driver

[PATCH 17/17] octeontx2-af: Support for NIXLF's UCAST/PROMISC/ALLMULTI modes

From: Sunil Goutham By default NIXLF is set in UCAST mode. This patch adds a new mailbox message which when sent by a RVU PF changes this default mode. When promiscuous mode is needed, the reserved promisc entry for each of RVU PF is setup to match against ingress channel number only, so that
