If MPRQ is enabled, a PMD-private mempool is allocated. For ConnectX-4 Lx,
the minimum number of strides is 512 which ConnectX-5 supports 8. This
results in quite small number of elements for the MPRQ mempool. For
example, if the size of Rx ring is configured as 512, only one MPRQ buffer
can cover the whole ring. If there's only one Rx queue is configured. In
the following code in mlx5_mprq_alloc_mp(), desc is 1 and obj_num will be
36 as a result.
desc *= 4;
obj_num = desc + MLX5_MPRQ_MP_CACHE_SZ * priv->rxqs_n;
However, rte_mempool_create_empty() has a sanity check to refuse large
per-lcore cache size compared to the number of elements. Cache flush
threshold should not exceed the number of elements of a mempool. For the
above example, the threshold is 32 * 1.5 = 48 which is larger than 36 and
it fails to create the mempool.

This commit fixes an infinite loop bug that could occur
if the i40e AVX2 driver is used, and high traffic rates
cause the mempool from which the rxq pulls mbufs to become
empty.
The result would be an infinite loop of checking if we
should perform an rx rearm, calling the function and an
error return due the the mempool being emtpy.
The fix is to align the code in the AVX2 driver with the
SSE driver, where an if() is used instead of a while(),
allowing the thread to return from i40e rx function even
if the mempool is empty.

The below commit has added a graph based expansion logic for RSS rule to
satisfy Verbs requirements. With this logic, for example, the rule:
flow create 0 ingress pattern eth / end actions rss queues 0 1 end types
ipv4-tcp ipv6-tcp end / end
will be expanded into the rules:
flow create 0 ingress pattern eth / ipv4 / tcp / end actions rss queues 0 1
end types ipv4-tcp ipv6-tcp end / end
flow create 0 ingress pattern eth / ipv6 / tcp / end actions rss queues 0 1
end types ipv4-tcp ipv6-tcp end / end
flow create 0 ingress pattern eth / end actions queue index 0 / end
The below commit defined two graphs:
1. graph for the tunnel case which starts from the ETH item
2. graph for the non-tunnel case which starts from the ETH item
The graphs are ignoring the VLAN case. Hence rules with VLAN item will
fail to traverse the graph and it will result in flow rule creation error.
Adding the VLAN item to the existing graphs will not work as the flow
engine will reject any VLAN item without a specific vid.
To solve this case two new graphs were added (for the tunnel and
non-tunnel case) which contain the VLAN item and are being used only
when the VLAN item exists in the flow pattern.
Two cases left un-covered for the inner RSS:
1. The case were VLAN exists in the pattern as part of the inner headers
2. The case were VLAN exists in the pattern both in the outer and the
inner headers
Solving those cases will require to add two more graphs.
Holding a VLAN for the overlay network is not common, the subnets are
usually defined by the tunnel protocol, for example the VXLAN vni.
Hence adding those two graphs seems like an overkill at this point.
Based on needs one can add those to provide the full support.

There are dedicated QP attributes, tunnel offload flag and mask, which
must be configured in order to allow part of the HW tunnel offloads.
So, if a QP is pointed by a tunnel flow, the above QP attributes
should be configured.
The mask configuration is wrongly only performed if an internal RSS was
configured by the user, while there is no reason to condition the
tunnel offloads in RSS configurations.
Consequently, some of the tunnel offloads was not performed by the HW
when a tunnel flow was configured, for example, the packet tunnel
types was not reported to the user.
Replace the internal RSS condition with the tunnel flow condition.
