Pull InfiniBand/RDMA changes from Roland Dreier: - Add ocrdma hardware driver for Emulex IB-over-Ethernet adapters - Add generic and mlx4 support for "raw" QPs: allow suitably privileged applications to send and receive arbitrary packets directly to/from the hardware - Add "doorbell drop" handling to the cxgb4 driver - A fairly large batch of qib hardware driver changes - A few fixes for lockdep-detected issues - A few other miscellaneous fixes and cleanups Fix up trivial conflict in drivers/net/ethernet/emulex/benet/be.h. * tag 'rdma-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband: (53 commits) RDMA/cxgb4: Include vmalloc.h for vmalloc and vfree IB/mlx4: Fix mlx4_ib_add() error flow IB/core: Fix IB_SA_COMP_MASK macro IB/iser: Fix error flow in iser ep connection establishment IB/mlx4: Increase the number of vectors (EQs) available for ULPs RDMA/cxgb4: Add query_qp support RDMA/cxgb4: Remove kfifo usage RDMA/cxgb4: Use vmalloc() for debugfs QP dump RDMA/cxgb4: DB Drop Recovery for RDMA and LLD queues RDMA/cxgb4: Disable interrupts in c4iw_ev_dispatch() RDMA/cxgb4: Add DB Overflow Avoidance RDMA/cxgb4: Add debugfs RDMA memory stats cxgb4: DB Drop Recovery for RDMA and LLD queues cxgb4: Common platform specific changes for DB Drop Recovery cxgb4: Detect DB FULL events and notify RDMA ULD RDMA/cxgb4: Drop peer_abort when no endpoint found RDMA/cxgb4: Always wake up waiters in c4iw_peer_abort_intr() mlx4_core: Change bitmap allocator to work in round-robin fashion RDMA/nes: Don't call event handler if pointer is NULL RDMA/nes: Fix for the ORD value of the connecting peer ...

IB/mlx4: Put priority bits in WQE of IBoE MLX QP

2012-05-08T18:48:09+00:00

Otherwise CM packets going over MLX QP1 get fixed scheduling priority 0. We want CM packets to get the same scheduling priority, and therefore map to the same SQ (Schedule Queue) and eventually TC (Traffic Class), as the application requested for the actual QP used for the connection.

net/mlx4_en: Force user priority by QP attribute

2012-04-05T09:08:03+00:00

Instead of relying on HW to change schedule queue by UP, schedule queue is fixed for a tx_ring, and UP in WQE is ignored in this aspect. This resolves two issues with untagged traffic: 1. untagged traffic has no UP in packet which is needed for QoS. The change above allows setting the schedule queue (and by that the UP) of such a stream. 2. BlueFlame uses the same field used by vlan tag. So forcing UP from QPC allows using BF for untagged but prioritized traffic. In old firmware that force UP is not supported, untagged traffic will not subject to QoS. Because UP is set by QP, need to always have a tx ring per UP, even if pfcrx module paramter is false. Signed-off-by: Amir Vadai Signed-off-by: David S. Miller

mlx4_en: dont change mac_header on xmit

2012-02-26T19:22:05+00:00

A driver xmit function is not allowed to change skb without special care. mlx4_en_xmit() should not call skb_reset_mac_header() and instead should use skb->data to access ethernet header. This removes a dumb test : if (ethh && ethh->h_dest) Also remove this slow mlx4_en_mac_to_u64() call, we can use get_unaligned() to get faster code.

net/mlx4_en: adding loopback support

2011-11-27T22:17:04+00:00

Device must be in promiscuous mode or DMAC must be same as the host MAC, or else packet will be dropped by the HW rx filtering. Signed-off-by: Amir Vadai Signed-off-by: David S. Miller

net/mlx4: move RSS related definitions to be global

2011-11-27T22:17:03+00:00

Towards adding RSS support for IB drivers/application who use the mlx4 HW, make the RSS related definitions global and change the mlx4_en driver to use them. Signed-off-by: Or Gerlitz Signed-off-by: Shlomo Pongratz Signed-off-by: David S. Miller

IB/mlx4: Add support for XRC QPs

2011-10-13T16:44:18+00:00

Support the creation of XRC INI and TGT QPs. To handle the case where a CQ or PD is not provided, we allocate them internally with the xrcd. Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

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

mlx4_core: Fix location of counter index in QP context struct

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