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>
