2015-12-15fcoe: Use CHECKSUM_PARTIAL to indicate CRC offloadTom Herbert
When setting up CRC offload set ip_summed to CHECKSUM_PARTIAL instead of CHECKSUM_UNNECESSARY. This is consistent with the definition of CHECKSUM_PARTIAL. The only driver that seems to be advertising NETIF_F_FCOE_CRC is ixgbe. AFICT the driver does not look at ip_summed for FCOE and just assumes that CRC is being offloaded.

2015-12-15sctp: Rename NETIF_F_SCTP_CSUM to NETIF_F_SCTP_CRCTom Herbert
The SCTP checksum is really a CRC and is very different from the standards 1's complement checksum that serves as the checksum for IP protocols. This offload interface is also very different. Rename NETIF_F_SCTP_CSUM to NETIF_F_SCTP_CRC to highlight these differences. The term CSUM should be reserved in the stack to refer to the standard 1's complement IP checksum.

2015-12-15Merge branch 'mlxsw-bridge-vlan-offloading'David S. Miller
Ido Schimmel says: ==================== This patchset introduces support for the offloading of 802.1D bridges between VLAN devices. These can either be VLAN devices configured on top of the physical ports or on top of LAG devices. Patches 1-2 deal with the necessary infrastructure changes needed in order to enable the above. The main change is that switchdev drivers can now know the device from which the switchdev op originated from. Patches 3-10 lay the groundwork for 802.1D bridges support in the mlxsw driver, with patch 4 doing most of the heavy lifting. Patch 11 finally offloads these bridges to hardware by listening to the notifications sent when the VLAN device joins or leaves a bridge. It is very similar to the already existing 802.1Q bridge we support. Patches 12-14 add minor modifications to allow one to bridge a VLAN device configured on top of LAG. ==================== Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2015-12-15mlxsw: spectrum: Add support for VLAN devices on top of LAGIdo Schimmel
When creating a VLAN device on top of LAG, we are basically creating a vPort on top of each of the port netdevs member in the LAG. Therefore, these vPorts should inherit both the LAG status and LAG ID from the underlying port netdevs. In addition, when the VLAN device joins or leaves a bridge each of the underlying vPorts should know about it and act accordingly. This is achieved by propagating the VLAN event down to the lower devices. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2015-12-15mlxsw: spectrum: Add support for VLAN devices bridgingIdo Schimmel
All the member VLAN devices in a bridge need to share the same vFID. To achieve that, expand the vFID struct to include the associated bridge device (or lack of) and allow one to lookup a vFID based on a bridge device. When joining a bridge, lookup the relevant vFID or create one if none exists. Next, make the VLAN device use the vFID. Leaving a bridge can either occur because a user removed the VLAN device from a bridge or because the VLAN device was deleted by the user. In the latter case the bridge's teardown sequence is invoked after the hardware vPort is already gone. Therefore, when unlinking the VLAN device from the real device, check if the associated vPort is bridged and act accordingly. The bridge's notification will be ignored in this case. Note that bridging a VLAN interface with an ordinary port netdev is currently not supported, but not forbidden. This will be addressed in a follow-up patchset.

2015-12-15mlxsw: spectrum: Handle VLAN devices linking / unlinkingIdo Schimmel
When a VLAN interface is configured on top of a physical port we should associate the VLAN device with the matching vPort. Likewise, when it's removed, we should revert back to the underlying port netdev. While not a must, this is consistent with port netdevs and also provides a more accurate error printing via netdev_err() and friends.

2015-12-15mlxsw: spectrum: Adjust FDB notifications for VLAN devicesIdo Schimmel
FDB notifications contain the FID and port (or LAG ID) on which the MAC was learned. In the case of the 802.1Q bridge one can easily derive the matching VID - as FID equals VID - and generate the appropriate notification for the software bridge. With VLAN devices this is no longer the case, as these are associated with a vFID. Solve that by converting the FID to a vFID and lookup the matching VLAN device. From that derive the VID and whether learning (and learning sync) should occur. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

We previously used only one flood table for packets classified to vFIDs. However, since we are going to add support for bridges between VLAN interfaces (mapped to vFIDs) we need to add one more flood table.

2015-12-15mlxsw: spectrum: Split vFID range in twoIdo Schimmel
Up until now we used a 1:1 mapping - based on VID - to map a VLAN interface to a vFID. However, a different scheme is needed in order to support bridges between VLAN interfaces, as all the member interfaces - which can have different VIDs - need to share the same vFID. Solve that by splitting the vFID range in two: 1. Non-bridged VLAN interfaces 2. Bridged VLAN interfaces When a VLAN interface is created, assign it the next available vFID in the first range, unless one already exists for that VID or number of vFIDs in the range was exceeded. When interface is removed, free the vFID, unless other interfaces are mapped to it. To accomplish the above: 1. Store the VID to vFID mapping in a new struct (mlxsw_sp_vfid), which has a global context and holds a reference count. 2. Create a vPort (dummy in case of bridge SELF invocation) on top of of the physical port and hold a reference to the associated vFID. vfid vfid +-------------+ +-------------+ | vfid | | vfid | | vid +---> ... | vid | | nr_vports | | nr_vports | +------+------+ +------+------+ | +-----------------------+-------+ | | vport vport +-------------+ +-------------+ | ... | | ... | | *vfid +---> ... | *vfid +---> ... | ... | | ... | +------+------+ +------+------+ | | port port +-------------+ +-------------+ | ... | | ... | | vports_list | | vports_list | | ... | | ... | +-------------+ +-------------+ swXpY swXpZ Next patches in the series will add the missing infrastructure for the second range and transfer vPorts between the two ranges according to the received notifications.

2015-12-15mlxsw: spectrum: Allocate active VLANs only for port netdevsIdo Schimmel
When adding support for bridges between VLAN interfaces, we'll introduce a new entity called a vPort, which is a represntation of the VLAN interface in the hardware. The main difference between a vPort and a physical port is that several FIDs can be bound to the latter, whereas only one (called a vFID) can be bound to the first. Therefore, it makes sense to use the same struct to represent the two, but to only allocate the 'active_vlans' bitmap in case of a physical port.

2015-12-15switchdev: Pass original device to port netdev driverIdo Schimmel
switchdev drivers need to know the netdev on which the switchdev op was invoked. For example, the STP state of a VLAN interface configured on top of a port can change while being member in a bridge. In this case, the underlying driver should only change the STP state of that particular VLAN and not of all the VLANs configured on the port. However, current switchdev infrastructure only passes the port netdev down to the driver. Solve that by passing the original device down to the driver as part of the required switchdev object / attribute. This doesn't entail any change in current switchdev drivers. It simply enables those supporting stacked devices to know the originating device and act accordingly.

Alex Duyck changes e1000_up() to void since it always returned 0, also by making it void, we can drop some code since we no longer have to worry about non-zero return values. Aaron Sierra removes GS40G specific defines and functions since the i210 internal PHY can be accessed with the access functions shared by 82580, i350 and i354 devices. Also removes the code to add the PHY address into the PCDL register address, since there is no real reason to do so. Joe updates the cable length function reports all four pairs true min, max and average cable length for i210. Also updated ethtool to use enum-based labels instead of hard coded values. Benjamin Poirier cleans up code that is never reachable since MSI-X interrupts are not shared in e1000e. Also removes the ICR read in the other interrupt handler, since the information is not needed and IMS is configured such that the only link status change can trigger the other interrupt handler. Fixed in MSI-X mode, there is no handler for the LSC interrupt so there is no point in writing that to ICS now that we always assume other interrupts are caused by LSC. ==================== Signed-off-by: David S.

2015-12-14e1000e: Fix msi-x interrupt automaskBenjamin Poirier
Since the introduction of 82574 support in e1000e, the driver has worked on the assumption that msi-x interrupt generation is automatically disabled after each irq. As it turns out, this is not the case. Currently, rx interrupts can fire multiple times before and during napi processing. This can be a problem for users because frames that arrive in a certain window (after adapter->clean_rx() but before napi_complete_done() has cleared NAPI_STATE_SCHED) generate an interrupt which does not lead to napi_schedule(). These frames sit in the rx queue until another frame arrives (a tcp retransmit for example). While the EIAC and CTRL_EXT registers are properly configured for irq automask, the modification of IAM in e1000_configure_msix() is what prevents automask from working as intended. This patch removes that erroneous write and fixes interrupt rearming for tx interrupts. It also clears IAME from CTRL_EXT. This is not strictly necessary for operation of the driver but it is to avoid disruption from potential programs that access the registers directly, like `ethregs -c`.

bd1060a1d671 ("sock, cgroup: add sock->sk_cgroup") added global spinlock cgroup_sk_update_lock but erroneously skipped initializer leading to uninitialized spinlock warning. Fix it by using DEFINE_SPINLOCK().

2015-12-14igb: Remove GS40G specific defines/functionsAaron Sierra
The I210 internal PHY can be accessed just as well with the access functions shared by 82580, I350, and I354 devices. A side effect of relying on the common functions, is that I210 cable length support is folded back into the common case which effectively reverts the following commit: commit 59f301046b276f87483b3afa3201a4273def06a9 Author: Carolyn Wyborny <carolyn.wyborny@intel.com> Date: Wed Oct 10 04:42:59 2012 +0000 igb: Update get cable length function for i210/i211 Cc: Carolyn Wyborny <carolyn.wyborny@intel.com> Signed-off-by: Aaron Sierra <asierra@xes-inc.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2015-12-14e1000e: Switch e1000e_up to void, drop code checking for error resultAlexander Duyck
The function e1000e_up always returns 0. As such we can convert it to a void and just ignore the results. This allows us to drop some code in a couple spots as we no longer need to worry about non-zero return values.

2015-12-14hv_netvsc: Fix race condition on Multi-Send Data fieldHaiyang Zhang
In commit 2a04ae8acb14 ("hv_netvsc: remove locking in netvsc_send()"), the locking for MSD (Multi-Send Data) field was removed. This could cause a race condition between RNDIS control messages and data packets processing, because these two types of traffic are not synchronized. This patch fixes this issue by sending control messages out directly without reading MSD field. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Reviewed-by: K. Y.
