net/mlx4: Fix the check in attaching steering rules

2018-05-23T01:36:27+00:00

[ Upstream commit 6dc06c08bef1c746ff8da33dab677cfbacdcad32 ]

Our previous patch (cited below) introduced a regression
for RAW Eth QPs.

Fix it by checking if the QP number provided by user-space
exists, hence allowing steering rules to be added for valid
QPs only.

net/mlx4_core: Avoid delays during VF driver device shutdown

2018-01-17T17:55:35+00:00

[ Upstream commit 4cbe4dac82e423ecc9a0ba46af24a860853259f4 ]

Some Hypervisors detach VFs from VMs by instantly causing an FLR event
to be generated for a VF.

In the mlx4 case, this will cause that VF's comm channel to be disabled
before the VM has an opportunity to invoke the VF device's "shutdown"
method.

For such Hypervisors, there is a race condition between the VF's
shutdown method and its internal-error detection/reset thread.

The internal-error detection/reset thread (which runs every 5 seconds) also
detects a disabled comm channel. If the internal-error detection/reset
flow wins the race, we still get delays (while that flow tries repeatedly
to detect comm-channel recovery).

The cited commit fixed the command timeout problem when the
internal-error detection/reset flow loses the race.

This commit avoids the unneeded delays when the internal-error
detection/reset flow wins.

net/mlx4_core: Set initial admin GUIDs for VFs

2015-04-15T19:51:50+00:00

To have out of the box experience, the PF generates random GUIDs who
serve as the initial admin values.

net/mlx4_core: Manage alias GUID per VF

2015-04-15T19:51:50+00:00

Manages alias GUIDs per VF per port in the core layer.

This is a pre-step for managing alias GUIDs in a mode that the admin
GUID is returned via ib_query_gid() regardless of whether the SM
has approved it or not.

net/mlx4_en: Add RX-ALL support

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

Enabled when the device supports KEEP FCS and IGNORE FCS.

When the flag is set, pass all received frames up the stack,
even ones with invalid FCS, controlled by ethtool.

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: Warn users of depracated QoS Firmware

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

A new capability bit was introduced in the past to to differ devices
using the QoS ETS feature. The old was deprecated since then.
If driver sees device which set only the old capabilty, it will print
warning to user suggesting to upgrade the FW.

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: Added qos_vport QP configuration in VST mode

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

Granular QoS per VF feature introduce a new QP field, qos_vport.

PF administrator can connect VF QPs to a certain QoS Vport, to
inherit its proporties. Connecting QPs to the default QoS Vport
(defined as 0) is always allowed, even when there are no allocated VPPs.
At this point, only the default vport is connected to QPs.
