Simon Horman says: ==================== nfp: add flower app with representors this series adds a flower app to the NFP driver. It initialises four types of netdevs: * PF netdev - lower-device for communication of packets to device * PF representor netdev * VF representor netdevs * Phys port representor netdevs The PF netdev acts as a lower-device which sends and receives packets to and from the firmware. The representors act as upper-devices. For TX representors attach a metadata dst to the skb which is used by the PF netdev to prepend metadata to the packet before forwarding the firmware. On RX the PF netdev looks up the representor based on the prepended metadata received from the firmware and forwards the skb to the representor after removing the metadata. Control queues are used to send and receive control messages which are used to communicate configuration information with the firmware. These are in separate vNIC to the queues belonging to the PF netdev. The control queues are not exposed to use-space via a netdev or any other means. The first 9 patches of this series provide app-independent infrastructure to instantiate representors and the remaining 3 patches provide an app which uses this infrastructure. As the name implies this app is targeted at providing offload of TC flower. Flower offload - allowing classifiers to be attached to representor netdevs - is intended to be provided by follow-up patches at which point it will become the dominant feature of the app. Minor changes since v2 noted in changelogs of individual patches. Review of v1 and v2 of this patchset have been addressed either through discussion on-list or changes in this patchset. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Switches and modern SR-IOV enabled NICs may multiplex traffic from Port representators and control messages over single set of hardware queues. Control messages and muxed traffic may need ordered delivery. Those requirements make it hard to comfortably use TC infrastructure today unless we have a way of attaching metadata to skbs at the upper device. Because single set of queues is used for many netdevs stopping TC/sched queues of all of them reliably is impossible and lower device has to retreat to returning NETDEV_TX_BUSY and usually has to take extra locks on the fastpath. This patch attempts to enable port/representative devs to attach metadata to skbs which carry port id. This way representatives can be queueless and all queuing can be performed at the lower netdev in the usual way. Traffic arriving on the port/representative interfaces will be have metadata attached and will subsequently be queued to the lower device for transmission. The lower device should recognize the metadata and translate it to HW specific format which is most likely either a special header inserted before the network headers or descriptor/metadata fields. Metadata is associated with the lower device by storing the netdev pointer along with port id so that if TC decides to redirect or mirror the new netdev will not try to interpret it. This is mostly for SR-IOV devices since switches don't have lower netdevs today.

Three patches from Tariq, Introduces page reuse mechanism in non-Striding RQ RX datapath, we allow the the RX descriptor to reuse its allocated page as much as it could, until the page is fully consumed. RX page reuse reduces the stress on page allocator and improves RX performance especially with high speeds (100Gb/s). Next four patches of the series from Or allows to offload tc flower matching on ttl/hoplimit and header re-write of hoplimit. The rest of the series from Yotam and Or enhances mlx5 to support FW flashing through the mlxfw module, in a similar manner done by the mlxsw driver.

If pci_alloc_irq_vectors() fails, the driver aborts the probe and the ENA network device is never brought up.

ENA driver post Rx buffers through the Rx submission queue for the ENA device to fill them with receive packets. Each Rx buffer is marked with req_id in the Rx descriptor. Newer ENA devices could consume the posted Rx buffer in out of order, and as result the corresponding Rx completion queue will have Rx completion descriptors with non contiguous req_id(s) In this change the driver holds two rings. The first ring (called free_rx_ids) is a mapping ring. It holds all the unused request ids. The values in this ring are from 0 to ring_size -1. When the driver wants to allocate a new Rx buffer it uses the head of free_rx_ids and uses it's value as the index for rx_buffer_info ring. The req_id is also written to the Rx descriptor Upon Rx completion, The driver took the req_id from the completion descriptor and uses it as index in rx_buffer_info. The req_id is then return to the free_rx_ids ring. This patch also adds statistics to inform when the driver receive out of range or unused req_id. Note: free_rx_ids is only accessible from the napi handler, so no locking is required Signed-off-by: NNetanel Belgazal <netanel@amazon.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Commit 31fd8581 ("bpf: permits narrower load from bpf program context fields") permits narrower load for certain ctx fields. The commit however will already generate a masking even if the prog-specific ctx conversion produces the result with narrower size. For example, for __sk_buff->protocol, the ctx conversion loads the data into register with 2-byte load. A narrower 2-byte load should not generate masking. For __sk_buff->vlan_present, the conversion function set the result as either 0 or 1, essentially a byte. The narrower 2-byte or 1-byte load should not generate masking. To avoid unnecessary masking, prog-specific *_is_valid_access now passes converted_op_size back to verifier, which indicates the valid data width after perceived future conversion. Based on this information, verifier is able to avoid unnecessary marking. Since we want more information back from prog-specific *_is_valid_access checking, all of them are packed into one data structure for more clarity.
