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.

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

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. Derived from patch by Eli Cohen Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

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

mlx4_en: Reporting HW revision in ethtool -i

2011-03-23T19:24:20+00:00

HW revision is derived from device ID and rev id. Signed-off-by: Eugenia Emantayev Signed-off-by: Yevgeny Petrilin Signed-off-by: David S. Miller

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. Signed-off-by: Igor Yarovinsky 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.
