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.

mlx4: Wake on LAN support

2011-03-23T19:24:19+00:00

The driver queries the FW for WOL support.
Ethtool get/set_wol is implemented accordingly.
Only magic packets are supported at the time.

mlx4: Changing interrupt scheme

2011-03-23T19:24:18+00:00

Adding a pool of MSI-X vectors and EQs that can be used explicitly by mlx4_core
customers (mlx4_ib, mlx4_en). The consumers will assign their own names to the
interrupt vectors. Those vectors are not opened at mlx4 device initialization,
opened by demand.
Changed the max number of possible EQs according to the new scheme, no longer relies on
on number of cores.
The new functionality is exposed through mlx4_assign_eq() and mlx4_release_eq().
Customers that do not use the new API will get completion vectors as before.

IB/mlx4: Handle protocol field in multicast table

2011-01-12T22:49:17+00:00

The newest device firmware stores IB vs. Ethernet protocol in two bits
in members_count field of multicast group table (0: Infiniband, 1:
Ethernet).  When changing the QP members count for a multicast group,
it important not to reset this information.  When calling multicast
attach first time, the protocol type should be specified.  In this
patch we always set it IB, but in the future we will handle Ethernet
too.  When looking for a QP, the protocol type shoud be checked too.

IB/mlx4: Add VLAN support for IBoE

2010-10-25T17:20:39+00:00

This patch allows IBoE traffic to be encapsulated in 802.1Q tagged
VLAN frames.  The VLAN tag is encoded in the GID and derived from it
by a simple computation.

The netdev notifier callback is modified to catch VLAN device
addition/removal and the port's GID table is updated to reflect the
change, so that for each netdevice there is an entry in the GID table.
When the port's GID table is exhausted, GID entries will not be added.
Only children of the main interfaces can add to the GID table; if a
VLAN interface is added on another VLAN interface (e.g. "vconfig add
eth2.6 8"), then that interfaces will not add an entry to the GID
table.
