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: New file for QoS related firmware commands

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

Create two new files fw_qos.h and fw_qos.c in mlx4_core module.

It gathers all relevant QoS firmware related commands etc, thus improving
encapsulation of the mlx4_core module. For now it contains the QoS existing
commands: mlx4_SET_PORT_SCHEDULER and mlx4_SET_PORT_PRIO2TC.

net/mlx4: Add RSS support for fragmented IP datagrams

2015-04-02T20:24:50+00:00

Enable RSS support for fragmented IP packets, when device supports it.
Until now, fragmented IP packets were directed only to the default_qpn.
Since IP fragments (datagram) have no upper protocols (L3 IP packets),
hash is performed on 3-tuple - dst MAC, source IP and dest IP. The HW
makes sure that this holds for the 1st fragment too, so all fragments
go to the same QP.
