2017-04-20net: add netif_is_ovs_port helperJiri Pirko
To find out if a netdev is an OVS port. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-20mlxsw: spectrum: Teach mlxsw_sp_port_vlan_set to accept any vlan rangeJiri Pirko
So far, mlxsw_sp_port_vlan_set range is limited by MLXSW_REG_SPVM_REC_MAX_COUNT. In spectrum_switchdev code this is wrapped up by a helper function which actually does multiple calls to FW for bigger ranges. Move the code into mlxsw_sp_port_vlan_set and use it always. That allows caller not to care about the range. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-20mlxsw: spectrum_flower: Set dummy FID before forward actionJiri Pirko
HW requires the FID to be valid in order for the forward action to work. So regardless of the current FID validity, just set the dummy FID which would do the trick.

2017-04-20mlxsw: spectrum: Add dummy FID initializationJiri Pirko
For forwarding using ACL action, HW needs a valid FID to be setup. It does not actually use it, so it can be any valid FID. So create a dummy FID only for this purpose.

This is for the legacy floppy and ataflop drivers that currently abuse ->errors for this purpose.

Currently it's used by the lighnvm passthrough ioctl, but we'd like to make it private in preparation of block layer specific error code. Lighnvm already returns the real NVMe status anyway, so I think we can just limit it to returning -EIO for any status set. This will need a careful audit from the lightnvm folks, though.

We want our own clearly defined error field for NVMe passthrough commands, and the request errors field is going away in its current form. Just store the status and result field in the nvme_request field from hardirq completion context (using a new helper) and then generate a Linux errno for the block layer only when we actually need it. Because we can't overload the status value with a negative error code for cancelled command we now have a flags filed in struct nvme_request that contains a bit for this condition.
