This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines

ethdev: allow to get RSS hash functions and key

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.

app/testpmd: add engine that replies to ARP and ICMP echo requests

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).

app/testpmd: added new macfwd-retry mode

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.
