2018-12-07net: hns3: deletes unnecessary settings of the descriptor dataShiju Jose1-22/+5
This patch deletes unnecessary setting of the descriptor data to 0 for disabling error interrupts because it is already done by the hclge_cmd_setup_basic_desc function.

2018-12-07net: hns3: re-enable error interrupts on hw resetShiju Jose3-7/+10
This patch adds calling hclge_hw_error_set_state function to re-enable the error interrupts those will be disabled on the hw reset. Signed-off-by: Shiju Jose <shiju.jose@huawei.com> Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-12-07net: hns3: rename enable error interrupt functionsShiju Jose3-55/+34
This patch - renames the enable error interrupt functions. The reason is that these functions are used for both enable and disable error interrupts. - removes redundant logs from the enable error interrupt functions.

2018-12-07net: hns3: remove existing process error functions and reorder hw_blk tableShiju Jose3-475/+18
1.The command interface for queryng and clearing hw errors is changed, which requires the new process error functions to be added. This patch removes all the current process error functions and associated definitions. The new functions to handle ras errors would be added in this patch set. 2. Fixed order issue of the hw_blk table. Signed-off-by: Shiju Jose <shiju.jose@huawei.com> Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-12-07selftests: forwarding: Add PVID test case for VXLAN with VLAN-aware bridgesIdo Schimmel1-0/+70
When using VLAN-aware bridges with VXLAN, the VLAN that is mapped to the VNI of the VXLAN device is that which is configured as "pvid untagged" on the corresponding bridge port. When these flags are toggled or when the VLAN is deleted entirely, remote hosts should not be able to receive packets from the VTEP. Add a test case for above mentioned scenarios.

2018-12-07selftests: mlxsw: vxlan: Test FDB un/marking on VXLAN join/leavePetr Machata1-0/+177
When a VXLAN device is attached to an offloaded bridge, or when a front-panel port is attached to a bridge that already has a VXLAN device, mlxsw should offload the existing offloadable FDB entries. Similarly when VXLAN device is downed, the FDB entries are unoffloaded, and the marks thus need to be cleared. Similarly when a front-panel port device is attached to a bridge with a VXLAN device, or when VLAN flags are tweaked on a VXLAN port attached to a VLAN-aware bridge. Test that the replaying / clearing logic works by observing transitions in presence of offload marks under different scenarios.

2018-12-07mlxsw: spectrum_nve: Un/offload FDB on nve_fid_disable/enablePetr Machata1-0/+41
Any existing NVE FDB entries need to be offloaded when NVE is enabled for a given FID. Recent patches have added fdb_replay op for this, so just invoke it from mlxsw_sp_nve_fid_enable(). When NVE is disabled on a FID, any existing FDB offloaded marks need to be cleared on NVE device as well as on its bridge master. An op to handle this, fdb_clear_offload, has been added to FID ops and NVE ops in previous patches. Add code to resolve the NVE device, NVE type, and dispatch to both fdb_clear_offload ops.

2018-12-07mlxsw: spectrum: Add mlxsw_sp_fid_ops.fdb_clear_offloadPetr Machata2-0/+30
If there are any offloaded FDB entries at bridge master of an NVE device at the time that it's un-offloaded, their offloaded marks need to be cleared. How that is done depends on whether the bridge in question is vlan aware. Therefore add a per-FID-type operation. Implement the operation for the 802.1q and 802.1d bridges. Add and publish a function mlxsw_sp_fid_fdb_clear_offload() to dispatch to the new operation according to FID type.

If there are any offloaded FDB entries at an NVE device at the time that it's un-offloaded, their offloaded marks need to be cleared. How that is done depends on NVE device type, and therefore add a per-NVE-type operation. Implement the operation for the sole NVE device type currently supported by mlxsw, VXLAN.

2018-12-07mlxsw: spectrum_nve: Add mlxsw_sp_nve_ops.fdb_replayPetr Machata2-0/+11
A replay of FDB needs to be performed so that the FDB entries existing at the NVE device are offloaded. How the replay is done depends on NVE device type, and therefore add a per-NVE-type operation.

2018-12-07mlxsw: spectrum: Track NVE type at FIDsPetr Machata3-7/+25
A follow-up patch will add support for replay and for clearing of offload marks. These are NVE type-sensitive operations, and to be able to dispatch them properly, a FID needs to know what NVE type is attached to it. Therefore, track the NVE type at struct mlxsw_sp_fid. Extend mlxsw_sp_fid_vni_set() to take it as an argument, and add mlxsw_sp_fid_nve_type().

2018-12-07vxlan: Add vxlan_fdb_replay()Petr Machata2-0/+56
When a VXLAN device becomes relevant to a driver (such as when it is attached to an offloaded bridge), the driver will generally need to walk the existing FDB entries and offload them. Add a function vxlan_fdb_replay() to call a given notifier block for each FDB entry with a given VNI.

2018-12-07vxlan: Add a function to init switchdev_notifier_vxlan_fdb_infoPetr Machata1-23/+18
There are currently two places that need to initialize the notifier info structure, and one more is coming next when vxlan_fdb_replay() is introduced. These three instances have / will have very similar code that is easy to abstract away into a named function. Add such function, vxlan_fdb_switchdev_notifier_info(), and call it from vxlan_fdb_switchdev_call_notifiers() and vxlan_fdb_find_uc().
