When creating rdma interface without specifying a name, we need to
generate one instead of NULL.

TX queues must be created before RX queues on Mellanox cards in order to

In case of tx success after multiple retries, the last buffers to be
enqueued will be both enqueued for tx and freed.

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.

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.

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...).

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.
