2020-10-24rdma: implement striding rq for multiseg rxMohammed Hawari1-3/+13
This change leverages the striding RQ feature of ConnectX-5 adapters to support chained buffers on the RX path. In Striding RQ mode, WQE are SG lists of data segments, each mapped to a vlib_buffer. When a packet is received, it can consume one or multiple data segments belonging to the WQE, without wasting the whole WQE.

2020-03-16rdma: introduce direct verb for Cx4/5 txBenoît Ganne1-7/+69
Direct Verb allows for direct access to NIC HW rx/tx rings. This patch introduce TX direct verb support for Mellanox ConnectX-4/5 adapters. 'dv' mode must be explicitely selected at interface creation to benefit from this. Type: feature Change-Id: If830ba9f33db73299acdbddc68b5c09eaf6add98 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2020-01-08rdma: api: prepare support for direct verbBenoît Ganne1-0/+8
Prepare rdma interface creation API for direct verb support: - add new optional 'mode' parameters to select between ibverb or direct verb backend (optional, default to 'auto') - set default value for rxq_num (1), rxq_size (1024) and txq_size (1024) so they are now optional - bump default create value for rxq_size and txq_size to 1024 if unset (0) so they are coherent with default values above Type: feature Change-Id: Id9eae2b8eb0baaf34a0fcd55da6ad09515f57a93 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2019-05-24rdma: add support for promiscuous modeBenoît Ganne1-7/+4
rdma interfaces filter packets per MAC by default to share the physical interface between multiple users (eg. VPP and Linux). When configured in promiscuous mode, all packets will go to this interface, regardless of the MAC. All other interface will not receive anymore packet while it is in promiscuous mode. Promiscuous mode is needed (and automatically turned on) for L2 path (l2patch, xconnect, bridge...).

2019-03-28Add RDMA ibverb driver pluginBenoît Ganne1-0/+141
RDMA ibverb is a userspace API to efficiently rx/tx packets. This is an initial, unoptimized driver targeting Mellanox cards. Next steps should include batching, multiqueue and additional cards. Change-Id: I0309c7a543f75f2f9317eaf63ca502ac7a093ef9 Signed-off-by: Benoît Ganne <bganne@cisco.com>
