|\ | | | | | | | | | | | | | | | | | | | | | | | | | | Merge 'net' bug fixes into 'net-next' as we have patches that will build on top of them. This merge commit includes a change from Emil Goode (emilgoode@gmail.com) that fixes a warning that would have been introduced by this merge. Specifically it fixes the pingv6_ops method ipv6_chk_addr() to add a "const" to the "struct net_device *dev" argument and likewise update the dummy_ipv6_chk_addr() declaration.

| | | | | | | | | | | | | | | | | | | | MAC addresses assigned by the PF to VFs were not kept in the PF driver admin table. As a result, displaying the VF MACs from the PF interface to user space showed zero address where in fact the VF got non-zero address from the PF, fix that.

| * net/mlx4_core: Return -EPROBE_DEFER when a VF is probed before PF is ↵Jack Morgenstein2013-06-042-16/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sufficiently initialized In the PF initialization, SRIOV is enabled before the PF is fully initialized. This allows the kernel to probe the newly-exposed VFs before the PF is ready to handle them (nested probes). Have the probe method return the -EPROBE_DEFER value in this situation (instead of the VF probe method retrying its initialization in a loop, and returning -EIO on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel itself will retry the probe after a suitable delay.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mlx4 driver has a suboptimal memory allocation strategy for regular MTU=1500 frames, as it uses two page fragments : One of 512 bytes and one of 1024 bytes. This makes GRO less effective, as each GSO packet contains 8 MSS instead of 16 MSS. Performance of a single TCP flow gains 25 % increase with the following patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The different steering modes are global to the device, with DMFS being introduced after SRIOV was merged. Hence, SRIOV guests running legacy / older Linux kernels or non-Linux drivers may provide B0 steering directives when the hypervisor is using DMFS and fail. Under B0 only L2 steering rules are allowed, hence B0 is a subset of DMFS. Use this fact to enable such legacy guests to run by modifying the SRIOV B0 steering wrapper to translate guest B0 directives to DMFS ones when the device uses DMFS. The translated B0 rule has to be kept in the resource tracker as a B0 object to allow for lookup in case of detach.

| * net/mlx4_core: Disallow releasing VF QPs which have steering rulesHadar Hen Zion2013-03-211-8/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | VF QPs must not be released when they have steering rules attached to them. For that end, introduce a reference count field to the QP object in the SRIOV resource tracker which is incremented/decremented when steering rules are attached/detached to it. QPs can be released by VF only when their ref count is zero. Signed-off-by: Hadar Hen Zion <hadarh@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | On the resource tracker cleanup flow, the DMFS rules must be deleted before we destroy the QPs, else the HW may attempt doing packet steering to non existent QPs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I believe these error messages are already logged on allocation failure by warn_alloc_failed and so get a dump_stack on OOM. Remove the unnecessary additional error logging. Around these deletions: o Alignment neatening. o Remove unnecessary casts of dma_alloc_coherent. o Hoist assigns from ifs.
