2017-10-18net: ftgmac100: Request clock and set speedJoel Stanley
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 Machata
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.

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 Machata
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.

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.

register_netdevice() could fail early when we have an invalid dev name, in which case ->ndo_uninit() is not called. For tun device, this is a problem because a timer etc. are already initialized and it expects ->ndo_uninit() to clean them up. We could move these initializations into a ->ndo_init() so that register_netdevice() knows better, however this is still complicated due to the logic in tun_detach(). Therefore, I choose to just call dev_get_valid_name() before register_netdevice(), which is quicker and much easier to audit. And for this specific case, it is already enough.

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.

Link status query firmware messages originating from the VFs are forwarded to the PF. The driver handles these interactions in a workqueue for the VF and PF. The VF driver waits for the response from the PF in the workqueue. If the PF and VF driver are running on the same host and the work for both PF and VF are queued on the same workqueue, the VF driver may not get the response if the PF work item is queued behind it on the same workqueue. This will lead to the VF link query message timing out. To prevent this, we create a private workqueue for PFs instead of using the common workqueue. The VF query and PF response will never be on the same workqueue. Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")

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.

2017-10-14macvlan: Only update pkt_type if destination MAC address matchesAlexander Duyck
This patch updates the pkt_type to PACKET_HOST only if the destination MAC address matches on the on the source based macvlan. It didn't make sense to be updating broadcast, multicast, and non-local destined frames with PACKET_HOST. Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: David S.

2017-10-14macvlan: Only deliver one copy of the frame to the macvlan interfaceAlexander Duyck
This patch intoduces a slight adjustment for macvlan to address the fact that in source mode I was seeing two copies of any packet addressed to the macvlan interface being delivered where there should have been only one. The issue appears to be that one copy was delivered based on the source MAC address and then the second copy was being delivered based on the destination MAC address. To fix it I am just treating a unicast address match as though it is not a match since source based macvlan isn't supposed to be matching based on the destination MAC anyway.

2017-10-14hv_netvsc: Add initialization of tx_table in netvsc_device_add()Haiyang Zhang
tx_table is part of the private data of kernel net_device. It is only zero-ed out when allocating net_device. We may recreate netvsc_device w/o recreating net_device, so the private netdev data, including tx_table, are not zeroed. It may contain channel numbers for the older netvsc_device. This patch adds initialization of tx_table each time we recreate netvsc_device. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>
