2016-05-13e1000e: fix ethtool autoneg off for non-copperSteve Shih1-2/+10
This patch fixes the issues for disabling auto-negotiation and forcing speed and duplex settings for the non-copper media. For non-copper media, e1000_get_settings should return ETH_TP_MDI_INVALID for eth_tp_mdix_ctrl instead of ETH_TP_MDI_AUTO so subsequent e1000_set_settings call would not fail with -EOPNOTSUPP. e1000_set_spd_dplx should not automatically turn autoneg back on for forced 1000 Mbps full duplex settings for non-copper media.

This adds support in 2 ndo that allow PF to tweak the VF's view of the link - `ndo_set_vf_link_state' to allow it a view independent of the PF's, and `ndo_set_vf_rate' which would allow the PF to limit the VF speed.

This adds support for PF control over the VF vlan configuration. I.e., `ip link ... vf <x> vlan <vid>' should now be supported. 1. <vid> != 0 => VF receives [unknowingly] only traffic tagged by <vid> and tags all outgoing traffic sent by VF with <vid>. 2. <vid> == 0 ==> Remove the pvid configuration, reverting to previous.

Adding a PCI callback for `sriov_configure' and a new PCI device id for the VF [+ Some minor changes to accomodate differences between PF and VF at the qede]. Following this, VF creation should be possible and the entire subset of existing PF functionality that's allow to VFs should be supported.

2016-05-12qed: Align TLVsYuval Mintz6-2/+375
As the VF infrastructure is supposed to offer backward/forward compatibility, the various types associated with VF<->PF communication should be aligned across all various platforms that support IOV on our family of adapters. This adds a couple of currently missing values, specifically aligning the enum for the various TLVs possible in the communication between them. It then adds the PF implementation for some of those missing VF requests. This support isn't really necessary for the Linux VF as those VFs aren't requiring it [at least today], but are required by VFs running on other OSes. LRO is an example of one such configuration.

2016-05-12qed: Bulletin and LinkYuval Mintz5-6/+425
Up to this point, VF and PF communication always originates from VF. As a result, VF cannot be notified of any async changes, and specifically cannot be informed of the current link state. This introduces the bulletin board, the mechanism through which the PF is going to communicate async notifications back to the VF. basically, it's a well-defined structure agreed by both PF and VF which the VF would continuously poll and into which the PF would DMA messages when needed. [Bulletin board is actually allocated and communicated in previous patches but never before used] Based on the bulletin infrastructure, the VF can query its link status and receive said async carrier changes.

2016-05-12qed: IOV l2 functionalityYuval Mintz9-246/+1957
This adds sufficient changes to allow VFs l2-configuration flows to work. While the fastpath of the VF and the PF are meant to be exactly the same, the configuration of the VF is done by the PF. This diverges all VF-related configuration flows that originate from a VF, making them pass through the VF->PF channel and adding sufficient logic on the PF side to support them.

2016-05-12qed: IOV configure and FLRYuval Mintz13-11/+959
While previous patches have already added the necessary logic to probe VFs as well as enabling them in the HW, this patch adds the ability to support VF FLR & SRIOV disable. It then wraps both flows together into the first IOV callback to be provided to the protocol driver - `configure'. This would later to be used to enable and disable SRIOV in the adapter.

2016-05-12qed: Introduce VFsYuval Mintz23-186/+1777
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.

2016-05-12qed: Add VF->PF channel infrastructureYuval Mintz9-15/+580
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.

2016-05-12qed: Add CONFIG_QED_SRIOVYuval Mintz9-0/+650
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.

2016-05-11dsa: mv88e6xxx: Handle eeprom-length propertyAndrew Lunn2-0/+20
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.

2016-05-11net: l3mdev: Add hook in ip and ipv6David Ahern1-98/+91
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).

2016-05-10gtp: add initial driver for datapath of GPRS Tunneling Protocol (GTP-U)Pablo Neira3-0/+1382
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.
