Few bugs fixes in both configuration get and hash update where inputs
are not handled as expected by the ethdev layer.
RSS structure may not be totally usable, the PMD should try to take as
most information from it has it can when it is an hash update or it
should try to fill as most as possible in the configuration get.
This means that in the RSS configuration structure, the memory space for
the RSS hash key may not be present, but the PMD should consider the
hash field valid and process/set it.

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).
