1) Add a new function "rss_hash_conf_get" in the PMD API to retrieve the
current configuration of the RSS functions and/or of the RSS key used
by a NIC to compute the RSS hash of input packets.
The new function uses the existing data structure "rte_eth_rss_conf" for
returning the RSS hash configuration.
2) Add the ixgbe-specific function "ixgbe_dev_rss_hash_conf_get" and the
igb-specific function "eth_igb_rss_hash_conf_get" to retrieve the RSS
hash configuration of ixgbe and igb controllers respectively.
3) Add the command "show port X rss-hash [key]" in the testpmd application
to display the RSS hash configuration of port X.

The function cmd_config_rss_parsed() associated with the command
"port config rss all" required to first stop all ports, in order to
then entirely re-configure all ports with the new RSS hash computation
parameters.
Use now the new function rte_eth_dev_rss_hash_conf_update() that dynamically
only changes the RSS hash computation parameters of a port, without needing
to previously stop the port.

The DPDK dump functions are useful for remote debugging of an

is typically routed to /dev/null.
Instead change all these functions to take a stdio FILE * handle
instead. An application can then use open_memstream() to capture
the output.

Add a new specific packet processing engine in the "testpmd" application that
only replies to ARP requests and to ICMP echo requests.
For this purpose, a new "icmpecho" forwarding mode is provided that can be
dynamically selected with the following testpmd command:
set fwd icmpecho
before starting the receipt of packets on the selected ports.
Then, the "icmpecho" engine performs the following actions on all received
packets:
- replies to a received ARP request by sending back on the RX port a ARP
reply with a "sender hardware address" field containing the MAC address
of the RX port,
- replies to a ICMP echo request by sending back on the RX port a ICMP echo
reply, swapping the IP source and the IP destination address in the IP
header,
- otherwise, simply drops the received packet.
When replying to a received packet that was encapsulated into a VLAN tunnel,
the reply is sent back with the same VLAN identifier.
By default, the testpmd configures VLAN header stripping RX option on each
port.
This option is not managed by the icmpecho engine which won't detect
packets that were encapsulated into a VLAN.
To address this issue, the VLAN header stripping option must be previously
switched off with the following testpmd command:
vlan set strip off
When the "verbose" mode has been set with the testpmd command
"set verbose 1", the "icmpecho" engine displays informations about each
received packet.
The "icmpecho" forwarding engine can also be used to simply check port
connectivity at the hardware level (check that cables are well-plugged)
and at the software level (receipt of VLAN packets, for instance).

The expression (192 << 24) has an undefined behavior since:
- the integer constant 192 has type int, and
- 192 x 2^24 is not representable as an int.
Suffixing 192 with U defines a behavior since:
- the integer constant 192U has type unsigned int, and
- the value of (192U << 24) is defined as

a0cdfcf9 (use pcap-config to guess compilation flags),
ef5b2363 (fix build with empty LIBPCAP_CFLAGS) and
60191b89 (fix build when pcap_sendpacket is unavailable).
These patches are creating more problems than solving the initial one
(which was a build error with too old pcap libraries).
Since old pcap libraries are not that common, just revert them.

This adds a new forwarding mode to testpmd, whereby it will forward
packets, but on a transmit failure, it will wait a small amount of time
before retrying the transmit again. This mode can be useful in some
cases to set a zero-packet loss rate at the cost of overall throughput,
especially in cases where TX ring size/buffering is constrained, such as
with virtio.
