2017-03-30bonding: refine bond_fold_stats() wrap detectionEric Dumazet1-3/+8
Some device drivers reset their stats at down/up events, possibly fooling bonding stats, since they operate with relative deltas. It is nearly not possible to fix drivers, since some of them compute the tx/rx counters based on per rx/tx queue stats, and the queues can be reconfigured (ethtool -L) between the down/up sequence. Lets avoid accumulating 'negative' values that render bonding stats useless. It is better to lose small deltas, assuming the bonding stats are fetched at a reasonable frequency.

Preethi changes the default driver mode of operation to descriptor write-back for VF. Alex cleans up and addresses several issues in the way that i40e handles private flags. Modifies the driver to use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed. Refactors the driver by pulling the code responsible for fetching the receive buffer and synchronizing DMA into a single function. Also pulled the code responsible for handling buffer recycling and page counting and distributed it through several functions, so we can commonize the bits that handle either freeing or recycling the buffers. Cleans up the code in preparation for us adding support for build_skb(). Changed the way we handle the maximum frame size for the receive path so it is more consistent with other drivers. Paul enables XL722 to use the direct read/write method since it does not support the AQ command to read/write the control register. Christopher fixes a case where we miss an arq element if a new one is added before we enable interrupts and exit the loop. Jake cleans up a pointless goto statement. Also cleaned up a flag that was not being used. Carolyn does round 2 for adding a delay to the receive queue to accommodate the hardware needs. ==================== Signed-off-by: David S.

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.

2017-03-29Merge tag 'mlx5e-pedit' of ↵David S. Miller10-103/+537
git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux 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: David S.

2017-03-29i40e/i40evf: Change the way we limit the maximum frame size for RxAlexander Duyck6-27/+41
This patch changes the way we handle the maximum frame size for the Rx path. Previously we were rounding up to 2K for a 1500 MTU and then brining the max frame size down to MTU plus a fixed amount. With this patch applied what we now do is limit the maximum frame to 1.5K minus the value for NET_IP_ALIGN for standard MTU, and for any MTU greater than 1500 we allow up to the maximum frame size. This makes the behavior more consistent with the other drivers such as igb which had similar logic. In addition it reduces the test matrix for MTU since we only have two max frame sizes that are handled for Rx now.

This patch pulls out the code responsible for handling buffer recycling and page counting and distributes it through several functions. This allows us to commonize the bits that handle either freeing or recycling the buffers. As far as the page count tracking one change to the logic is that pagecnt_bias is decremented as soon as we call i40e_get_rx_buffer. It is then the responsibility of the function that pulls the data to either increment the pagecnt_bias if the buffer can be recycled as-is, or to update page_offset so that we are pointing at the correct location for placement of the next buffer.

2017-03-29i40e: remove a useless goto statementJacob Keller1-4/+0
The goto found here for when in MFP mode is pointless. It jumps to the end of a series of if blocks. However, right after this statement is a closing '}' for this if block, which will result in the program flow going to the exact same location as the goto statement indicates. Thus, regardless of whether we are in MFP mode, the program flow will resume from the same location. This arose due to various refactoring which did not notice that this goto became essentially a no-op. To properly understand this diff you will need to view a larger context than is given by default.

2017-03-29i40e: Clean up handling of private flagsAlexander Duyck2-85/+112
This patch cleans up and addresses several issues in the way that i40e handles private flags. Previously the code was choosing fixed bits and trying to match them up with strings in a somewhat haphazard way. This resulted in the possibility for adding a new bit and causing a mismatch as the private flags are linear bits starting at 0, and the private flags in the driver were split up over a group specific to the PF and a group that was global. What this change does is define an array of structs used to represent the private flags. Contained within the structs are the bits necessary to know which flags to set and/or clear depending on the state of the bit. By doing this we can add new bits in the future with minimal overhead and avoid creating possible mis-matches should we need to remove a flag based on compile options.

2017-03-29qed: Send pf-flr as part of initializationMintz, Yuval4-0/+28
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.

2017-03-29qed: Move to new load request schemeTomer Tayar8-58/+497
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.

2017-03-29qed: Correct HW stop flowTomer Tayar6-135/+142
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.

2017-03-29soc: qcom: smd: Transition client drivers from smd to rpmsgBjorn Andersson10-77/+82
By moving these client drivers to use RPMSG instead of the direct SMD API we can reuse them ontop of the newly added GLINK wire-protocol support found in the 820 and 835 Qualcomm platforms. As the new (RPMSG-based) and old SMD implementations are mutually exclusive we have to change all client drivers in one commit, to make sure we have a working system before and after this transition.

vxlan driver already implicitly supports installing of external fdb entries with NTF_EXT_LEARNED. This patch just makes sure these entries are not aged by the vxlan driver. An external entity managing these entries will age them out. This is consistent with the use of NTF_EXT_LEARNED in the bridge driver.
