When replenishing Rx ring, there're always buffered slots reserved
between consumed entries and HW owned entries. These have to be filled
with fake mbufs to protect from possible overflow rather than
optimistically expecting successful replenishment which can cause
deadlock with small-sized queue.

This commit extends the testpmd application with new forwarding engine
that demonstrates the use of ethdev traffic management APIs and softnic
PMD for QoS traffic management.
In this mode, 5-level hierarchical tree of the QoS scheduler is built
with the help of ethdev TM APIs such as shaper profile add/delete,
shared shaper add/update, node add/delete, hierarchy commit, etc.
The hierarchical tree has following nodes; root node(x1, level 0),
subport node(x1, level 1), pipe node(x4096, level 2),
tc node(x16348, level 3), queue node(x65536, level 4).
During runtime, each received packet is first classified by mapping the
packet fields information to 5-tuples (HQoS subport, pipe, traffic class,
queue within traffic class, and color) and storing it in the packet mbuf
sched field. After classification, each packet is sent to softnic port
which prioritizes the transmission of the received packets, and
accordingly sends them on to the output interface.
To enable traffic management mode, following testpmd command is used;
$ ./testpmd -c c -n 4 --vdev
'net_softnic0,hard_name=0000:06:00.1,soft_tm=on' -- -i
--forward-mode=tm

With the upstream rdma-core, to enable Rx CQE compression,
mlx5dv_create_cq() in Direct Verbs has to be used instead of regular
Verbs call (ibv_create_cq()). And if the size of CQE is 128 bytes,
compression is supported only by certain devices. Thus, it has to be
decided by checking the capability bits.

Add RSS support according to the RSS configuration.
A special case is handled, when the pattern does not cover the RSS hash
configuration request such as:
flow create 0 ingress pattern eth / end actions rss queues 0 1 end / end
In such situation with the default configuration of testpmd RSS i.e. IP,
it should be converted to 3 Verbs flow to handle correctly the request:
1. IPv4 flow, an extra IPv4 wildcard specification needs to be added in
the conversion.
2. IPv6 flow, same as for IPv4.
3. Ethernet followed by any other protocol on which no RSS can be
performed and thus the traffic will be redirected to the first queue
of the user request.
The same kind of issue is handled if the RSS is performed only on UDPv4
or UDPv6 or TCPv*.
This does not handle a priority conflict which can occurs if the user
adds several colliding flow rules. Currently in the example above, the
request is already consuming 2 priorities (1 for IPv4/IPV6 matching
rule priority and one for Ethernet matching rule priority + 1).
