IB/mlx4: Use flow counters on IBoE ports

2011-07-19T04:04:36+00:00

Allocate flow counter per Ethernet/IBoE port, and attach this counter
to all the QPs created on that port.  Based on patch by Eli Cohen
.

mlx4_core: Add network flow counters

2011-07-19T04:04:34+00:00

ConnectX devices support a set of flow counters that can be attached
to a set containing one or more QPs.  Each such counter tracks receive
and transmit packets and bytes of these QPs.  This patch queries the
device to check support for counters, handles initialization of the
HCA to enable counters, and initializes a bitmap allocator to control
counter allocations.  Derived from patch by Eli Cohen .

mlx4_core: Fix location of counter index in QP context struct

2011-07-19T04:04:33+00:00

Fix the address handle portion of the QP context structure to have the
correct bit location for the counter index field.

mlx4_core: Read extended capabilities into the flags field

2011-07-19T04:04:32+00:00

Query another dword containing up to 32 extended device capabilities
and merge it into struct mlx4_caps.flags.  Update the code that
handles the current extended device capabilities (e.g UDP RSS, WoL,
vep steering, etc) to use the extended device cap flags field instead
of a field per extended capability.  Initial patch done by Eli Cohen
.

mlx4_core: Extend capability flags to 64 bits

2011-07-19T04:04:32+00:00

The latest firmware adds a second dword containing more device flags,
so extend the device capabilities flags field from 32 to 64 bits.

mlx4: Add blue flame support for kernel consumers

2011-03-23T19:24:23+00:00

Using blue flame can improve latency by allowing the HW to more efficiently
access the WQE. This patch presents two functions that are used to allocate or
release HW resources for using blue flame; the caller need to supply a struct
mlx4_bf object when allocating resources. Consumers that make use of this API
should post doorbells to the UAR object pointed by the initialized struct
mlx4_bf;

mlx4_en: Enabling new steering

2011-03-23T19:24:22+00:00

The mlx4_en module now uses the new steering mechanism.
The RX packets are now steered through the MCG table instead
of Mac table for unicast, and default entry for multicast.
The feature is enabled through INIT_HCA

mlx4: generalization of multicast steering.

2011-03-23T19:24:21+00:00

The same packet steering mechanism would be used both for IB and Ethernet,
Both multicasts and unicasts.
This commit prepares the general infrastructure for this.
