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).
