This adds the qed VFs for the first time - The vfs are limited functions, with a very different PCI bar structure [when compared with PFs] to better impose the related security demands associated with them. This patch includes the logic neccesary to allow VFs to successfully probe [without actually adding the ability to enable iov]. This includes diverging all the flows that would occur as part of the pci probe of the driver, preventing VF from accessing registers/memories it can't and instead utilize the VF->PF channel to query the PF for needed information.

Communication between VF and PF is based on a dedicated HW channel; VF will prepare a messge, and by signaling the HW the PF would get a notification of that message existance. The PF would then copy the message, process it and DMA an answer back to the VF as a response. The messages themselves are TLV-based - allowing easier backward/forward compatibility. This patch adds the infrastructure of the channel on the PF side - starting with the arrival of the notification and ending with DMAing the response back to the VF. It also adds a dummy-response as reference, as it only lays the groundwork of the communication; it doesn't really add support of any actual messages.

Add support for a new Kconfig option for qed* driver which would allow [eventually] the support in VFs. This patch adds the necessary logic in the PF to learn about the possible VFs it will have to support [Based on PCI configuration space and HW], and prepare a database with an entry per-VF as infrastructure for future interaction with said VFs.

Samuel Ortiz says: ==================== NFC 4.7 pull request This is the first NFC pull request for 4.7. With this one we mainly have: - Support for NXP's pn532 NFC chipset. The pn532 is based on the same microcontroller as the pn533, but it talks to the host through i2c instead of USB. By separating the pn533 driver into core and PHY parts, we can not add the i2c layer and support the pn532 chipset. - Support for NCI's loopback mode. This is a testing mode where each packet received by the NFCC is sent back to the DH, allowing the host to test that the controller can receive and send data. - A few ACPI related fixes for the STMicro drivers, in order to match the device tree naming scheme. - A bunch of cleanups for the st-nci and the st21nfca STMicro drivers. ==================== Signed-off-by: NDavid S.

Saeed Mahameed says: ==================== Mellanox 100G mlx5 CQE compression Introducing ConnectX-4 CQE (Completion Queue Entry) compression feature for mlx5 etherent driver. CQE Compressing reduces PCI overhead by coalescing and compressing multiple CQEs into a single merged CQE. Successful compressing improves message rate especially for small packet traffic. CQE Compressing in details: Instead of writing full CQEs to memory, multiple almost identical CQEs are merged and compressed. Information that is shared between the CQEs is written once, regardless of the number of compressed CQEs. In addition, only the unique information (small amount of bytes compared to full CQE size) is written per CQE. CQE Compression Block: This block contains multiple compressed CQEs. CQE Compression Block contains a single copy of CQEs properties which are shared between all the compressed CQEs (called Title, see below) and multiple mini CQEs (CQEs in compressed form). Title: The Title holds information which is shared between all the compressed CQEs in the CQE Compression Block. In each Compression Block there is only a single Title regardless of the number of compressed CQEs. Mini CQE: A CQE in compressed form that holds some data needed to extract a single full CQE, for example 8 Bytes instead of 64 Bytes. The shared information between all compressed CQEs, which belong to the same CQE Compression Block called Title, is written once, and only the unique information in each compressed CQE, for example 8 bytes, is written per compressed CQE, called mini CQE. Since CQE Compression can add overhead to the software (CPU), it will be only enabled on "weak/slow" PCI slots, where it can actually help.

Andrew Lunn says: ==================== More enabler patches for DSA probing The complete set of patches for the reworked DSA probing is too big to post as once. These subset contains some enablers which are easy to review. Eventually, the Marvell driver will instantiate its own internal MDIO bus, rather than have the framework do it, thus allows devices on the bus to be listed in the device tree. Initialize the main mutex as soon as it is created, to avoid lifetime issues with the mdio bus. A previous patch renamed all the DSA probe functions to make room for a true device probe. However the recent merging of all the Marvell switch drivers resulted in mv88e6xxx going back to the old probe name. Rename it again, so we can have a driver probe function. Add minimum support for the Marvell switch driver to probe as an MDIO device, as well as an DSA driver. Later patches will then register this device with the new DSA core framework. Move the GPIO reset code out of the DSA code. Different drivers may need different reset mechanisms, e.g. via a reset controller for memory mapped devices. Don't clutter up the core with this. Let each driver implement what it needs. master_dev is no longer needed in the switch drivers, since they have access to a device pointer from the probe function. Remove it. Let the switch parse the eeprom length from its one device tree node. This is required with the new binding when the central DSA platform device no longer exists. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

A switch can export an attached EEPROM using the standard ethtool API. However the switch itself cannot determine the size of the EEPROM, and multiple sizes are allowed. Thus a device tree property is supported to indicate the length of the EEPROM. Parse this property during device probe, and implement a callback function to retrieve it.

Resetting the switch is something the driver does, not the framework. So move the parsing of this property into the driver.

David Ahern says: ==================== net: vrf: Fixup PKTINFO to return enslaved device index Applications such as OSPF and BFD need the original ingress device not the VRF device; the latter can be derived from the former. To that end move the packet intercept from an rx handler that is invoked by __netif_receive_skb_core to the ipv4 and ipv6 receive processing. IPv6 already saves the skb_iif to the control buffer in ipv6_rcv. Since the skb->dev has not been switched the cb has the enslaved device. Make the same happen for IPv4 by adding the skb_iif to inet_skb_parm and set it in ipv4 code after clearing the skb control buffer similar to IPv6. From there the pktinfo can just pull it from cb with the PKTINFO_SKB_CB cast. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 David Ahern 提交于
Currently the VRF driver uses the rx_handler to switch the skb device to the VRF device. Switching the dev prior to the ip / ipv6 layer means the VRF driver has to duplicate IP/IPv6 processing which adds overhead and makes features such as retaining the ingress device index more complicated than necessary. This patch moves the hook to the L3 layer just after the first NF_HOOK for PRE_ROUTING. This location makes exposing the original ingress device trivial (next patch) and allows adding other NF_HOOKs to the VRF driver in the future. dev_queue_xmit_nit is exported so that the VRF driver can cycle the skb with the switched device through the packet taps to maintain current behavior (tcpdump can be used on either the vrf device or the enslaved devices).

This is an initial implementation of a netdev driver for GTP datapath (GTP-U) v0 and v1, according to the GSM TS 09.60 and 3GPP TS 29.060 standards. This tunneling protocol is used to prevent subscribers from accessing mobile carrier core network infrastructure. This implementation requires a GGSN userspace daemon that implements the signaling protocol (GTP-C), such as OpenGGSN [1]. This userspace daemon updates the PDP context database that represents active subscriber sessions through a genetlink interface. For more context on this tunneling protocol, you can check the slides that were presented during the NetDev 1.1 [2]. Only IPv4 is supported at this time.
