The option of sending a packet on the ll2 and dropping it exists in hardware and was not used until now, thus not exposed. The iWARP unaligned MPA flow requires this functionality for flushing the tx queue. Signed-off-by:

When more than one ll2 queue is opened ( that is not an OOO queue ) ll2 code does not have enough information to determine whether the queue is the main one or not, so a new field is added to the acquire input data to expose the control of determining whether the queue is the main queue or a secondary queue.

iWARP uses 3 ll2 connections, the maximum number of bds is known during connection setup. This patch modifies the static array in the ll2_tx_packet descriptor to be a flexible array and significantlly reduces memory size. In addition, some redundant fields in the ll2_tx_packet were removed, which also contributed to decreasing the descriptor size. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: Offload bridge device mrouter Yotam says: Similarly to a bridged port, the bridge device itself can be configured by the user to be an mrouter port. In this case, all multicast traffic should be forwarded to it. Make the mlxsw Spectrum driver offload these directives to the Spectrum hardware. Patches 1 and 2 add a new switchdev notification for bridge device mrouter port status and make the bridge module notify about it. Patches 3-5 change the mlxsw Spectrum driver to handle these notifications by adding the Spectrum router port to the bridge MDB entries. v1->v2: - patch1: - Don't add the MDB_RTR_TYPE_TEMP state and use the timer_pending to distinguish between learning-on and learning-off states ==================== Signed-off-by: -

Support the SWITCHDEV_ATTR_ID_BRIDGE_MROUTER port attribute switchdev notification. To do that, add the mrouter flag to struct mlxsw_sp_bridge_device, which indicates whether the bridge device was set to be mrouter port. This field is set when: - A new bridge is created, where the value is taken from the kernel bridge value. - A switchdev SWITCHDEV_ATTR_ID_BRIDGE_MROUTER notification is sent. In addition, change the bridge MID entries to include the router port when the bridge device is configured to be mrouter port. The MID entries are updated in the following cases: - When a new MID entry is created, update the router port according to the bridge mrouter state. - When a SWITCHDEV_ATTR_ID_BRIDGE_MROUTER notification is sent, update all the bridge's MID entries. This is aligned with the case where a bridge slave is configured to be mrouter port. Signed-off-by:

In Spectrum, MDB entries point to MID entries, that indicate which ports a packet should be forwarded to. Add the support in creating MID entries that forward the packet to the Spectrum router port. This will be later used to handle the bridge mrouter port switchdev notifications. Signed-off-by:

In Spectrum hardware, the router port is a virtual port that is the gateway to the routing mechanism. Hence, in order for a packet to be L3 forwarded, it must first be L2 forwarded to the router port inside the hardware. Further patches in this patchset are going to introduce support in bridge device used as an mrouter port. In this case, the router port index will be needed in order to update the MDB entries to include the router port. Thus, export the mlxsw_sp_router_port function, which returns the index of the Spectrum router port. Signed-off-by:

Add an access function that, given a bridge netdevice, returns whether the bridge device is currently an mrouter or not. The function uses the already existing br_multicast_is_router function to check that. This function is needed in order to allow ports that join an already existing bridge to know the current mrouter state of the bridge device. Together with the bridge device mrouter ports switchdev notifications, it is possible to have full offloading of the semantics of the bridge device mcast router state. Due to the fact that the bridge multicast router status can change in packet RX path, take the multicast_router bridge spinlock to protect the read. Signed-off-by:

Add the SWITCHDEV_ATTR_ID_BRIDGE_MROUTER switchdev notification type, used to indicate whether the bridge is or isn't mrouter. Notify when the bridge changes its state, similarly to the already existing bridged port mrouter notifications. The notification uses the switchdev_attr.u.mrouter boolean flag to indicate the current bridge mrouter status. Thus, it only indicates whether the bridge is currently used as an mrouter or not, and does not indicate the exact mrouter state of the bridge (learning, permanent, etc.). Signed-off-by:

Jakub Kicinski says: ==================== nfp: bpf ABIv2 and multi port This series migrates our eBPF offload from old PoC firmware to a redesigned, faster and more feature rich FW. Marking support is dropped for now. We have to teach the JIT about encoding local memory accesses (one of NFP memory types). There is also code to populate the ECC of instructions (PoC had ECC protection on instruction store disabled). There is also a minor ld_field fix and all 64 bit shifts can now be encoded. ==================== Signed-off-by: -
Jakub Kicinski authored
ld_field instruction is a bit special because the encoding uses two source registers and one of them becomes the output. We do need to pass the dst register to our encoding helpers though, otherwise the "write both banks" flag will not be observed. Signed-off-by:

Datapath ABI version 2 stores the packet information in LMEM instead of NNRs. We also have strict restrictions on which GPRs we can use. Only GPRs 0-23 are reserved for BPF. Adjust the static register locations and "ABI" registers. Note that packet length is packed with other info so we have to extract it into one of the scratch registers, OTOH since LMEM can be used in restricted operands we don't have to extract packet pointer.

Most instructions have special fields which allow switching between base and extended Local Memory pointers. Introduce those to register encoding, we will use the extra LM pointers to access high addresses of the stack. Signed-off-by:

NFP LMEM is a large, indirectly accessed register file. There are two basic indirect access registers. Each access operation may either use offset (up to 8 or 16 words) or perform post decrement/increment. Add encodings of LMEM indexes as instruction operands. Signed-off-by:

Remove the register renumbering optimization. To implement calling map and other helpers we need more strict register layout. We can't freely reassign register numbers. This will have the effect of running in 4 context/thread mode, which should be OK since we are moving towards integrating the BPF closer with FW app datapath anyway, and the target datapath itself runs in 4 context mode.
