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: NEli Cohen <eli@mellanox.co.il> Signed-off-by: NDavid S.

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.

The ConnectX Programmer's Reference Manual states that the "SO" bit must be set when posting Fast Register and Local Invalidate send work requests. When this bit is set, the work request will be executed only after all previous work requests on the send queue have been executed. (If the bit is not set, Fast Register and Local Invalidate WQEs may begin execution too early, which violates the defined semantics for these operations) This fixes the issue with NFS/RDMA reported in <http://lists.openfabrics.org/pipermail/general/2009-April/059253.html> Signed-off-by: NJack Morgenstein <jackm@dev.mellanox.co.il> Cc: <stable@kernel.org> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

ConnectX devices support checksum generation and verification of TCP and UDP packets for UD IPoIB messages. This patch checks if the HCA supports this and sets the IB_DEVICE_UD_IP_CSUM capability flag if it does. It implements support for handling the IB_SEND_IP_CSUM send flag and setting the csum_ok field in receive work completions.

ConnectX HCA supports shrinking WQEs, so that a single work request can be made of multiple units of wqe_shift. This way, WRs can differ in size, and do not have to be a power of 2 in size, saving memory and speeding up send WR posting. Unfortunately, if we do this then the wqe_index field in CQEs can't be used to look up the WR ID anymore, so our implementation does this only if selective signaling is off. Further, on 32-bit platforms, we can't use vmap() to make the QP buffer virtually contigious. Thus we have to use constant-sized WRs to make sure a WR is always fully within a single page-sized chunk. Finally, we use WRs with the NOP opcode to avoid wrapping around the queue buffer in the middle of posting a WR, and we set the NoErrorCompletion bit to avoid getting completions with error for NOP WRs. However, NEC is only supported starting with firmware 2.2.232, so we use constant-sized WRs for older firmware. And, since MLX QPs only support SEND, we use constant-sized WRs in this case. When stamping during NOP posting, do stamping following setting of the NOP WQE valid bit. Signed-off-by: NMichael S.

Inline data segments in send WQEs are not allowed to cross a 64 byte boundary. We use inline data segments to hold the UD headers for MLX QPs (QP0 and QP1). A send with GRH on QP1 will have a UD header that is too big to fit in a single inline data segment without crossing a 64 byte boundary, so split the header into two inline data segments.

Add an InfiniBand driver for Mellanox ConnectX adapters. Because these adapters can also be used as ethernet NICs and Fibre Channel HBAs, the driver is split into two modules: mlx4_core: Handles low-level things like device initialization and processing firmware commands. Also controls resource allocation so that the InfiniBand, ethernet and FC functions can share a device without stepping on each other. mlx4_ib: Handles InfiniBand-specific things; plugs into the InfiniBand midlayer.
