I found a bug by: 0. boot and start dhcp client 1. echo mem > /sys/power/state 2. resume back immediately 3. don't touch dhcp client to renew the lease 4. ping the gateway. No acks Usually, after step2, the DHCP lease isn't expired, so in theory we should resume all back. But in fact, it doesn't. It turns out the rx mode isn't resumed correctly. This patch fixes it by adding mvneta_set_rx_mode(dev) in the resume hook if interface is running. Signed-off-by:

Or Gerlitz says: ==================== mlx5e-pedit 2017-03-28 This series adds support for offloading modifications of packet headers using ConnectX-5 HW header re-write as an action applied during packet steering. The offloaded SW mechanism is TC's pedit action. The offloading is supported for E-Switch steering of VF traffic in the SRIOV switchdev mode and for NIC (non eswitch) RX. One use-case for this offload on virtual networks, is when the hypervisor implements flow based router such as Open-Stack's DVR, where L2 headers of guest packets re-written with routers' MAC addresses and the IP TTL is decremented. Another use case (which can be applied in parallel with routing) is stateless NAT where guest L3/L4 headers are re-written. The series is built as follows: the 1st six patches are preperations which don't yet add new functionality, patches 7-8 add the FW APIs (data-structures and commands) for header re-write, and patch nine allows offloading driver to access pedit keys. The 10th patch is somehow the core of the series, where we translate from the pedit way to represent set of header modification elements to the FW API for that same matter. Once a set of HW modification is established, we register it with the FW and get a modify header ID. When this ID is used with an action during packet steering, the HW applies the header modification on the packet. Patches 11 and 12 implement the above logic as an offload for pedit action for the NIC and E-Switch use-cases. I'd like to thanks Elijah Shakkour <elijahs@mellanox.com> for implementing and helping me testing this functionality on HW simulator, before it could be done with FW. ==================== Signed-off-by: -

mdio-boardinfo contains code that is helpful for platforms to register specific MDIO bus devices independent of how CONFIG_MDIO_DEVICE or CONFIG_PHYLIB will be selected (modular or built-in). In order to make that possible, let's do the following: - descend into drivers/net/phy/ unconditionally - make mdiobus_setup_mdiodev_from_board_info() take a callback argument which allows us not to expose the internal MDIO board info list and mutex, yet maintain the logic within the same file - relocate the code that creates a MDIO device into drivers/net/phy/mdio_bus.c - build mdio-boardinfo.o into the kernel as soon as MDIO_DEVICE is defined (y or m) Fixes: 90eff909 ("net: phy: Allow splitting MDIO bus/device support from PHYs") Fixes: 648ea013 ("net: phy: Allow pre-declaration of MDIO devices") Signed-off-by:

Andrew Lunn says: ==================== break include loop and dsa devlink support These two patches add very basic support for devlink to DSA, in preparation for playing with dpipe. The first patch is needed to break an include loop between netdevice.h, dsa.h and devlink.h. We need to remove dsa.h from netdevice.h. As a result, some files fail to compile, because they require includes pulled in via dsa.h. So this patch adds a number of includes in various places. The majority is within the network subsystem, but cifs also needs a few fixes. 0-day has been chewing on this for over a day now, and not found any breakage. But Arnd's randconfig might uncover something. ==================== Signed-off-by: -

There is an include loop between netdevice.h, dsa.h, devlink.h because of NETDEV_ALIGN, making it impossible to use devlink structures in dsa.h. Break this loop by taking dsa.h out of netdevice.h, add a forward declaration of dsa_switch_tree and netdev_set_default_ethtool_ops() function, which is what netdevice.h requires. No longer having dsa.h in netdevice.h means the includes in dsa.h no longer get included. This breaks a few other files which depend on these includes. Add these directly in the affected file.

Refactor interrupt moderation code for flexibility because parameters are different for 10G and 25G cards. Currently parameters (for 10G only) come from macros compiled-in to the PF and VF drivers; fix it so that parameters suitable for the card (10G or 25G) come from the NIC firmware via response to a command. Also bump up driver version to 1.5.1 to match newer NIC firmware version. Signed-off-by:

Yuval Mintz says: ==================== qed: load/unload mfw series This series correct the unload flow and greatly enhances its initialization flow in regard to interactions between driver and management firmware. Patch #1 makes sure unloading is done under management-firmware's 'criticial section' protection. Patches #2 - #4 move driver into using a newer scheme for loading in regard to the MFW; This newer scheme would help cleaning the device in case a previous instance has dirtied it [preboot, PDA, etc.]. Patches #5 - #6 let driver inform management-firmware on number of resources which are dependent on the non-management firmware used. Patch #7 then uses a new resource [BDQ] instead of some set value. ==================== Signed-off-by: -

Until now, qed used some port-defined value as BDQ index for both iSCSI and FCoE. As management firmware now treats BDQ as a resource and tells each PF its BDQ-range, start using a valure from that range instead. Signed-off-by:

Management firmware is used as an arbiter between the various PFs in matters of resources, but some of the resources that need to be divided are dependent on the non-management firmware used, so management firmware first needs to be told how many resources there are before trying to divide them. As part of the initialization sequence, driver would first inform the management firmware of the available resources under a dedicated resource lock, and afterwards request for various resources which might be based on the previous set values.

Global locking can't properly be used to synchronize between different PFs in all scenarios, as those instances might reside in different logical partitions [e.g., when a PF is assigned via PDA to some VM]. The management firmware provides a generic infrastructure for device locks. For each 'resource', it's guaranteed it could be acquired by at most a single PF at any given time [or by management firmware]. This patch adds the necessary logic in qed for utilizing said infrastructure, implementing lock/unlock internal APIs. Signed-off-by:

During HW initialization, driver would set various registers to their needed values - but it assumes all registers start at their reset-value, so there's no need to re-configure a register's default value. This assumption might be incorrect, e.g., in case of preboot driver running and initializing the driver prior to our driver. To overcome this, we now ask management firmware to initiate a PF-flr early during the initialization sequence. That would return everything in the PF's scope back to default and prevent previous configurations from still being applied. Signed-off-by:

Management firmware is used as an arbiter between the various PFs in regard to loading - it causes the various PFs to load/unload sequentially and informs each of its appropriate rule in the init. But the existing flow is too weak to handle some scenarios where PFs aren't properly cleaned prior to loading. The significant scenarios falling under this criteria: a. Preboot drivers in some environment can't properly unload. b. Unexpected driver replacement [kdump, PDA]. Modern management firmware supports a more intricate loading flow, where the driver has the ability to overcome previous limitations. This moves qed into using this newer scheme. Notice new scheme is backward compatible, so new drivers would still be able to load properly on top of older management firmwares and vice versa. Signed-off-by:

We'll soon need additional information, so start by changing the infrastructure to receive the initializing variables via a parameter struct. Signed-off-by:

Management firmware is used as arbiter between different PFs which are loading/unloading, but in order to use the synchronization it offers the contending configurations need to be applied either between their LOAD_REQ <-> LOAD_DONE or UNLOAD_REQ <-> UNLOAD_DONE management firmware commands. Existing HW stop flow utilizes 2 different functions: qed_hw_stop() and qed_hw_reset() which don't abide this requirement; Most of the closure is doing outside the scope of the unload request. This patch removes qed_hw_reset() and places the relevant stop functionality underneath the management firmware protection. Signed-off-by:

Parthasarathy Bhuvaragan says: ==================== tipc: subscription refcount simplifications The first patch makes the subscription refcount cleanup lockless and the second updates the subscription refcount policy. ==================== Signed-off-by: -
Ying Xue authored
When a new subscription object is inserted into name_seq->subscriptions list, it's under name_seq->lock protection; when a subscription is deleted from the list, it's also under the same lock protection; similarly, when accessing a subscription by going through subscriptions list, the entire process is also protected by the name_seq->lock. Therefore, if subscription refcount is increased before it's inserted into subscriptions list, and its refcount is decreased after it's deleted from the list, it will be unnecessary to hold refcount at all before accessing subscription object which is obtained by going through subscriptions list under name_seq->lock protection.

After a subscription object is created, it's inserted into its subscriber subscrp_list list under subscriber lock protection, similarly, before it's destroyed, it should be first removed from its subscriber->subscrp_list. Since the subscription list is accessed with subscriber lock, all the subscriptions are valid during the lock duration. Hence in tipc_subscrb_subscrp_delete(), we remove subscription get/put and the extra subscriber unlock/lock. After this change, the subscriptions refcount cleanup is very simple and does not access any lock. Acked-by:
