2017-10-18net: ftgmac100: Request clock and set speedJoel Stanley1-0/+26
According to the ASPEED datasheet, gigabit speeds require a clock of 100MHz or higher. Other speeds require 25MHz or higher. This patch configures a 100MHz clock if the system has a direct-attached PHY, or 25MHz if the system is running NC-SI which is limited to 100MHz. There appear to be no other upstream users of the FTGMAC100 driver it is hard to know the clocking requirements of other platforms. Therefore a conservative approach was taken with enabling clocks. If the platform is not ASPEED, both requesting the clock and configuring the speed is skipped.

2017-10-16mlxsw: spectrum: Drop refcounting of IPIP entriesPetr Machata2-30/+20
Formerly, IPIP entries were created lazily by next hops that referenced an offloadable IP-in-IP netdevice. However now that they are created eagerly as a reaction to events on such netdevices, the reference counting is useless. Hence drop it. The routes whose next hops reference an offloaded IP-in-IP netdevice actually linger around a bit after their device is unregistered. However, mlxsw_sp_ipip_entry_destroy() also destroys the backing loopback, and mlxsw_sp_rif_destroy() transitively (via mlxsw_sp_nexthop_rif_gone_sync()) calls mlxsw_sp_nexthop_ipip_fini(), which unlinks the IPIP entry from a next hop. Thus no dangling pointers are left behind for the brief window after netdevice is gone, but routes not yet.

2017-10-16mlxsw: spectrum: Support IPIP overlay VRF migrationPetr Machata3-3/+49
IPIP entries are created as soon as an offloadable device is created. That means that when such a device is later moved to a different VRF, the loopback device that backs the tunnel is wrong. Thus when an offloadable encapsulating netdevice moves from one VRF to another, make sure that the loopback is updated as necessary.

2017-10-16mlxsw: spectrum: Support decap-only IP-in-IP tunnelsPetr Machata3-10/+109
Current code for offloading IP-in-IP tunneling assumes that there is no decap without encap. But that's never true for IPv6 overlays, and is not true for IPv4 ones either, if net.ipv4.conf.*.rp_filter is unset. To support decap-only tunnels, an IPIP entry is now created as soon as an offloadable tunneling device is created. When that netdevice is up'd, a decap route is looked up and possibly offloaded. Thus decap is not handled implicitly as part of mlxsw_sp_ipip_entry_get() call anymore, but needs to be done explicitly after the get, if desired.

2017-10-16mlxsw: spectrum: Move netdevice NB to struct mlxsw_spPetr Machata2-7/+17
So far, all netdevice notifications that the driver cared about were related to its own ports, and mlxsw_sp could be retrieved from the netdevice's private data. For IP-in-IP offloading however, the driver cares about events on foreign netdevices, and getting at mlxsw_sp or router data structures from the handler is inconvenient. Therefore move the netdevice notifier blocks from global scope to struct mlxsw_sp to allow retrieval from the notifier block pointer itself.

git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Saeed Mahameed says: ==================== mlx5-updates-2017-10-11: IPoIB Multi Pkey support This series provides the support for IPoIB Multi Pkey. InfiniBand Pkeys are the equivalent of Ethernet vlans. Currently IPoIB device driver supports only default Pkey and IPoIB Pkey child interfaces are not supported with IPoIB offloads mode, this series will add the support for that by allowing creating mlx5 multiple IPoIB netdevices with a non-default Pkey. mlx5 IPoIB Pkey child interface is smaller version of mlx5i IPoIB interfaces and shares most of its resources with the parent IPoIB interface, namely RX steering and ring queue resources. The only mlx5 resources a child Pkey interface will be creating are the TX rings, since they should be assigned to a specific Pkey. mlx5i Pkey netdev is implemented via new mlx5e netdev profile implemented in mlx5/core/ipoib/ipoib_vlan.c. The series starts with a refactoring of mlx5e PTP and mlx5 clock implementation to move the code to be part of mlx5 core rather than mlx5e netdevice, in order to make mlx5 clock and PTP registration part of the core to be shared with mlx5e master Ethernet netdev/IPoIB parent netdev and mlx5_ib in the near future. Add the support for attaching multiple underlay QPs for the different Pkeys in mlx5 core RX steering. Add Pkey index to rdma_netdev to add the ability to set PKEY index to lower IPoIB offload netdev. Use hash-table to map between DQPN (Destination QP number) to child netdev for the IPoIB parent netdev to forward RX packets to the corresponding child Pkey netdev, since the RX rings are shared. The reset of the series adds the ipoib child Pkey: mlx5e netdev profile, netdev nods implementation and minimal set of ethtool callbacks. ==================== Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-10-13 This series contains updates to mqprio and i40e. Amritha introduces a new hardware offload mode in tc/mqprio where the TCs, the queue configurations and bandwidth rate limits are offloaded to the hardware. The existing mqprio framework is extended to configure the queue counts and layout and also added support for rate limiting. This is achieved through new netlink attributes for the 'mode' option which takes values such as 'dcb' (default) and 'channel' and a 'shaper' option for QoS attributes such as bandwidth rate limits in hw mode 1. Legacy devices can fall back to the existing setup supporting hw mode 1 without these additional options where only the TCs are offloaded and then the 'mode' and 'shaper' options defaults to DCB support. The i40e driver enables the new mqprio hardware offload mechanism factoring the TCs, queue configuration and bandwidth rates by creating HW channel VSIs. In this new mode, the priority to traffic class mapping and the user specified queue ranges are used to configure the traffic class when the 'mode' option is set to 'channel'. This is achieved by creating HW channels(VSI). A new channel is created for each of the traffic class configuration offloaded via mqprio framework except for the first TC (TC0) which is for the main VSI. TC0 for the main VSI is also reconfigured as per user provided queue parameters. Finally, bandwidth rate limits are set on these traffic classes through the shaper attribute by sending these rates in addition to the number of TCs and the queue configurations. Colin Ian King makes an array of constant values "constant". Alan fixes and issue where on some firmware versions, we were failing to actually fill out the phy_types which caused ethtool to not report any link types. Also hardened against a potentially malicious VF by not letting the VF to reset itself after requesting to change the number of queues (via ethtool), let the PF reset the VF to institute the requested changes. ==================== Signed-off-by: David S.

The mapping between the dqpn and the netdevice is done using a HT, each mlx5 IPoIB interface registers its mapping on creation.

2017-10-14net/mlx5e: IPoIB, Support for setting PKEY index to underlay QPAlex Vesker2-0/+10
Added a function to set PKEY index to IPoIB device driver using the already present set_id function. PKEY index is attached to the QP during state modification. Signed-off-by: Alex Vesker <valex@mellanox.com> Reviewed-by: Erez Shitrit <erezsh@mellanox.com>
2017-10-14net/mlx5: Support for attaching multiple underlay QPs to root flow tableAlex Vesker5-54/+171
Previous support allowed connecting only a single QPN to the FT. Now using a linked list multiple QPNs can be attached to the same FT. Supporting attaching multiple underlay QPs is required for PKEY support in which child and parent share the same FT. The actual attaching/detaching FW commands will be called inside the function symmetrically. This change requires a change in IPoIB open and close functions, the attaching/detaching to/from the FT is done each time we open/close.

2017-10-14net/mlx5e: IPoIB, Move underlay QP init/uninit to separate functionsAlex Vesker1-38/+70
During the creation of the underlay QP the PKEY index is unknown, the PKEY index is known only when calling ndo_open. PKEY index attached to the QP during state modification. Splitting the functions will also make the code symmetric and more readable. This split is also required for later PKEY support to be called with the PKEY index during ndo_open.

2017-10-14net/mlx5: PTP code migration to driver core sectionFeras Daoud11-382/+392
PTP code is moved to core section of mlx5 driver in order to share it between ethernet and infiniband. This movement involves the following changes: - Change mlx5e_ prefix to be mlx5_ - Add clock structs to Core - Add clock object to mlx5_core_dev - Call Init/Uninit clock from core init/cleanup - Rename mlx5e_tstamp to be mlx5_clock Signed-off-by: Feras Daoud <ferasda@mellanox.com> Signed-off-by: Eitan Rabin <rabin@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2017-10-14nfp: bpf: support direct packet access in TCJakub Kicinski1-2/+15
Add support for direct packet access in TC, note that because writing the packet will cause the verifier to generate a csum fixup prologue we won't be able to offload packet writes from TC, just yet, only the reads will work.

2017-10-14nfp: bpf: add support for direct packet access - readJakub Kicinski5-11/+105
In direct packet access bound checks are already done, we can simply dereference the packet pointer. Verifier/parser logic needs to record pointer type. Note that although verifier does protect us from CTX vs other pointer changes we will also want to differentiate between PACKET vs MAP_VALUE or STACK, so we can add the check already.
