mlx4: Move the Mellanox driver

2011-08-11T09:41:35+00:00

Moves the Mellanox driver into drivers/net/ethernet/mellanox/ and make the necessary Kconfig and Makefile changes. CC: Roland Dreier Signed-off-by: Jeff Kirsher

mlx4_core: Bump the driver version to 1.0

2011-07-22T05:55:02+00:00

Many features were added to this driver, so the driver version should change too. Signed-off-by: Dotan Barak Signed-off-by: Roland Dreier

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 . Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

mlx4: Sensing link type at device initialization

2011-04-08T03:36:12+00:00

When bringing the port up, performing a SENSE_PORT command To try and check to which physical link type (IB or Ethernet) the physical port is connected. In case there is no valid link partner, the port will come up as its supported default. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S. Miller

mlx4_core: maintain available field in bitmap allocator

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

Add mlx4_bitmap_avail() to give the number of available resources. We want to use this as a hint to whether to allocate a resources or not. This patch is introduced to be used with allocation blue flame registers. Signed-off-by: Eli Cohen Signed-off-by: David S. Miller

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; Signed-off-by: Eli Cohen Signed-off-by: David S. Miller

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 Signed-off-by: Yevgeny Petrilin Signed-off-by: David S. Miller

mlx4: Add support for promiscuous mode in the new steering model.

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

For Ethernet mode only, When we want to register QP as promiscuous, it must be added to all the existing steering entries and also to the default one. The promiscuous QP might also be on of "real" QPs, which means we need to monitor every entry to avoid duplicates and ensure we close an entry when all it has is promiscuous QPs. Same mechanism both for unicast and multicast. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S. Miller

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.

drivers/net/mlx4: Use %pV, pr_, printk_once

2010-07-16T02:05:17+00:00

Remove near duplication of format string constants by using the newly introduced vsprintf extention %pV to reduce text by 20k or so. $ size drivers/net/mlx4/built-in.o* text data bss dec hex filename 161367 1866 48784 212017 33c31 drivers/net/mlx4/built-in.o 142621 1866 46248 190735 2e90f drivers/net/mlx4/built-in.o.new Use printk_once as appropriate.
