2018-11-23switchdev: Add SWITCHDEV_PORT_OBJ_ADD, SWITCHDEV_PORT_OBJ_DELPetr Machata
An offloading driver may need to have access to switchdev events on ports that aren't directly under its control. An example is a VXLAN port attached to a bridge offloaded by a driver. The driver needs to know about VLANs configured on the VXLAN device. However the VXLAN device isn't stashed between the bridge and a front-panel-port device (such as is the case e.g. for LAG devices), so the usual switchdev ops don't reach the driver. VXLAN is likely not the only device type like this: in theory any L2 tunnel device that needs offloading will prompt requirement of this sort. This falsifies the assumption that only the lower devices of a front panel port need to be notified to achieve flawless offloading. A way to fix this is to give up the notion of port object addition / deletion as a switchdev operation, which assumes somewhat tight coupling between the message producer and consumer. And instead send the message over a notifier chain. To that end, introduce two new switchdev notifier types, SWITCHDEV_PORT_OBJ_ADD and SWITCHDEV_PORT_OBJ_DEL. These notifier types communicate the same event as the corresponding switchdev op, except in a form of a notification. struct switchdev_notifier_port_obj_info was added to carry the fields that the switchdev op carries. An additional field, handled, will be used to communicate back to switchdev that the event has reached an interested party, which will be important for the two-phase commit. The two switchdev operations themselves are kept in place. Following patches first convert individual clients to the notifier protocol, and only then are the operations removed.

2018-11-23switchdev: Add a blocking notifier chainPetr Machata
In general one can't assume that a switchdev notifier is called in a non-atomic context, and correspondingly, the switchdev notifier chain is an atomic one. However, port object addition and deletion messages are delivered from a process context. Even the MDB addition messages, whose delivery is scheduled from atomic context, are queued and the delivery itself takes place in blocking context. For VLAN messages in particular, keeping the blocking nature is important for error reporting. Therefore introduce a blocking notifier chain and related service functions to distribute the notifications for which a blocking context can be assumed.

2018-11-23switchdev: SWITCHDEV_OBJ_PORT_{VLAN, MDB}(): SanitizePetr Machata
The two macros SWITCHDEV_OBJ_PORT_VLAN() and SWITCHDEV_OBJ_PORT_MDB() expand to a container_of() call, yielding an appropriate container of their sole argument. However, due to a name collision, the first argument, i.e. the contained object pointer, is not the only one to get expanded. The third argument, which is a structure member name, and should be kept literal, gets expanded as well. The only safe way to use these two macros is therefore to name the local variable passed to them "obj". To fix this, rename the sole argument of the two macros from "obj" (which collides with the member name) to "OBJ". Additionally, instead of passing "OBJ" to container_of() verbatim, parenthesize it, so that a comma in the passed-in expression doesn't pollute the container_of() invocation.

After sending one of the initial LLC messages CONFIRM LINK or ADD LINK, there is already a wait for the LLC response. It does not make sense to wait another long time for a CLC DECLINE. Thus this patch introduces a shorter wait time for these cases. Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-11-23net/smc: allow fallback after clc timeoutsUrsula Braun
If connection initialization fails for the LLC CONFIRM LINK or the LLC ADD LINK step, fallback to TCP should be enabled. Thus the negative return code -EAGAIN should switch to a positive timeout reason code in these cases, and the internal CLC socket should not have a set sk_err.

Shannon Nelson updates the ixgbe kernel documentation to include IPsec hardware offload. Joe Perches cleans up whitespace issues in the igb driver. Jesse update the netdev kernel documentation for NETIF_F_GSO_UDP_L4 to align with the actual code. Also aligned all the NAPI driver code for all of the Intel drivers to implement the recommendations of Eric Dumazet to check the return code of the napi_complete_done() to determine whether or not to enable interrupts or exit poll. Paul E. McKenney replaces synchronize_sched() with synchronize_rcu() for ixgbe.

Previous versions of this series have been posted to linux-renesas-soc as RFC so V3 is the first actual version to make it to netdev. Based on the latest data sheet for R-Car Gen3 [1] and R-Car Gen2 [2] the following information is part of the EthernetAVB-IF overview page: Transfer speed: Supports transfer at 100 and 1000 Mbps Mode: Full-duplex mode It seems that the driver implementation is not matching the information provided in the friendly data sheet, and on top of this during run-time when changing PHY configuration of the link partner the Ethernet-AVB PHY seems to want to announce unsupported modes. [1] R-Car Series, 3rd Generation Rev.1.00 (Apr 2018) [2] R-Car Series, 2nd Generation Rev.2.00 (Feb 2016) Changes since V2: - Updated patch 1/2 to make use of phy_remove_link_mode() - Added Reviewed-by from Sergei - thanks!

2018-11-23ravb: Clean up duplex handlingMagnus Damm
Since only full-duplex operation is supported by the hardware, remove duplex handling code and keep the register setting of ECMR.DM fixed at 1.

2018-11-22{net, IB}/mlx4: Initialize CQ buffers in the driver when possibleDaniel Jurgens
Perform CQ initialization in the driver when the capability is supported by the FW. When passing the CQ to HW indicate that the CQ buffer has been pre-initialized. Doing so decreases CQ creation time. Testing on P8 showed a single 2048 entry CQ creation time was reduced from ~395us to ~170us, which is 2.3x faster.
