net/mlx4_en: Support ndo_get_vf_stats

2015-06-16T00:23:03+00:00

Implement the ndo to gather VF statistics through the PF.

All counters related to this VF are stored in a per slave
list, run over the slave's list and collect all statistics.

net/mlx4_core: Add helper to query counters

2015-06-16T00:23:02+00:00

This is an infrastructure step for querying VF and PF counters.

This code was in the IB driver, move it to the mlx4 core driver
so it will be accessible for more use cases.

net/mlx4_en: Add interface identify support

2015-04-02T20:25:03+00:00

Add support for the interface ethtool identify feature.

Make the physical port LED to blink with green and yellow colors.

The device handles the LED blink by itself (synchrous use of
set_phys_id), by returning 0 to ETHTOOL_ID_ACTIVE command.

net/mlx4: Add SET_PORT opcode modifiers enumeration

2015-04-02T20:25:03+00:00

The calls to SET_PORT used hard-code numbers, when supplying command's
opcode modifiers, fix that to use well defined constants.

net/mlx4_en: Enable TX rate limit per VF

2015-04-02T20:25:03+00:00

Support granular QoS per VF, by implementing the ndo_set_vf_rate.

Enforce a rate limit per VF when called, and enabled only for VFs in
VST mode with user priority supported by the device.

We don't enforce VFs to be in VST mode at the moment of configuration,
but rather save the given rate limit and enforce it when the VF is
moved to VST with user priority which is supported (currently 0).

VST<->VGT or VST qos value state changes are disallowed when a rate
limit is configured. Minimum BW share is not supported yet.

net/mlx4: Add mlx4_SET_VPORT_QOS implementation

2015-04-02T20:25:02+00:00

Add the SET_VPORT_QOS device command, which is ntended for virtual
granular QoS configuration per VF in SRIOV mode. The SET_VPORT_QOS
command sets and queries QoS parameters of a VPort. Each priority
allowed for a VPort is assigned with a share of the BW, and a BW
limitation. QoS parameters can be modified at any time, but must be
initialized before any QP is associated with the VPort.

net/mlx4: Add mlx4_ALLOCATE_VPP implementation

2015-04-02T20:25:02+00:00

Implements device ALLOCATE_VPP command, to be used for granular QoS
configuration of VFs by the PF device. Defines and queries the amount
of VPPs assigned to each port, and the amount of VPPs assigned to each
priority of each port. Once the total VPPs are split between the priorities
of a port, they may be assigned with a share of the BW or a rate limit.

Split into two functions (get/set) whoch are supplied with
mlx4_alloc_vpp_context and physical port number.

net/mlx4_core: Add basic elements for QCN

2015-03-07T02:50:02+00:00

Add device capability, firmware command opcode and etc prior elements
needed for QCN suppprt. Disable SRIOV VF view/access for QCN is disabled.

While here, remove a redundant offset definition into the
QUERY_DEV_CAP mailbox.

net/mlx4_core: Port aggregation low level interface

2015-02-05T00:14:24+00:00

Implement the hardware interface required for port aggregation.

1. Disable RX port check on receive - don't perform a validity check
that matches to QP's port and the port where the packet is received.

2. Virtual to physical port remap - configure virtual to physical port
mapping. Port remap capability for virtual functions.

net/mlx4_core: Adjust command timeouts to conform to the firmware spec

2015-01-28T01:12:57+00:00

The firmware spec states that the timeout for all commands should be 60 seconds.

In the past, the spec indicated that there were several classes of timeout
(short, medium, and long).  The driver has these different timeout classes.
We leave the class differentiation in the driver as-is (to protect against any
future spec changes), but set the timeout for all classes to be 60 seconds.

In addition, we fix a few commands which had hard-coded numeric timeouts specified.
