2020-10-24rdma: implement striding rq for multiseg rxMohammed Hawari1-118/+319
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.

allocation, the remainder modulo 8 must be returned to the pool so that the number of kept buffers is a multiple of 8. Type: fix Change-Id: Ifd97b03ea220300e7e6fe81a8ff4a25060fea6c1 Signed-off-by: Mohammed Hawari <mohammed@hawari.fr>

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.

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.
