ConnectX-4 adapters do not have a constant indirection table size, which is
set at runtime from the number of RX queues. The maximum size is retrieved
using a hardware query and is normally 512.
Since the current RETA API cannot handle a variable size, any query/update
command causes it to be silently updated to RSS_INDIRECTION_TABLE_SIZE
entries regardless of the original size.
Also due to the underlying type of the configuration structure, the maximum
size is limited to RSS_INDIRECTION_TABLE_SIZE (currently 128, at most 256
entries).
A port stop/start must be done to apply the new RETA configuration.

Removing this structure reduces the size of SG and non-SG RX queue elements
significantly to improve performance.
An nice side effect is that the mbuf pointer is now fully stored in
struct rxq_elt instead of relying on the WR ID data offset hack.

This is the same implementation as mlx4.

In its current state, this driver implements the bare minimum to initialize
itself and Mellanox ConnectX-4 adapters without doing anything else
(no RX/TX for instance). It is disabled by default since it is based on the
mlx4 driver and also depends on libibverbs.
