2020-03-16rdma: introduce direct verb for Cx4/5 txBenoît Ganne4-73/+549
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>

2020-02-18rdma: fix bug related to ring bufferElias Rudberg1-2/+2
Fix a bug that caused some input packets to be dropped due to errors of the type 'ip4 length > l2 length'. The change is related to the second call to the rdma_device_input_bufs() function that happens when the end of the ring buffer is reached.

2020-01-08rdma: api: prepare support for direct verbBenoît Ganne7-10/+79
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>

2019-07-23api: binary api cleanupDave Barach1-1/+1
Multiple API message handlers call vnet_get_sup_hw_interface(...) without checking the inbound sw_if_index. This can cause a pool_elt_at_index ASSERT in a debug image, and major disorder in a production image. Given that a number of places are coded as follows, add an "api_visible_or_null" variant of vnet_get_sup_hw_interface, which returns NULL given an invalid sw_if_index, or a hidden sw interface: - hw = vnet_get_sup_hw_interface (vnm, sw_if_index); + hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index); if (hw == NULL || memif_device_class.index != hw->dev_class_index) return clib_error_return (0, "not a memif interface"); Rename two existing xxx_safe functions -> xxx_or_null to make it obvious what they return.

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-1/+1
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

2019-05-24rdma: add support for promiscuous modeBenoît Ganne2-71/+145
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...).
