Martin Stein a73ef9fc06 app/ping: fix destination MAC on ARP replies
The ARP destination MAC was set to the Ethernet source MAC which is not
necessarily the MAC of the other ARP peer. Instead use the ARP source MAC of
the ARP request.

The 'ping' component continuously sends ICMP Echo or UDP requests to a given
IP host and waits for the corresponding ICMP Echo or UDP replies. For each
successfull ICMP Echo or UDP handshake it prints a short statistic. The ICMP
data field gets filled with the letters of the alphabet ('a' to 'z') repeatedly.


Configuration
~~~~~~~~~~~~~

This is an example configuration of the component which shows the default
value for each attribute except 'config.dst_ip' and 'config.interface':

! <config interface="10.0.0.72/24"
!         dst_ip="10.0.0.24"
!         dst_port="50000"
!         protocol="icmp"
!         period_sec="5"
!         verbose="no"
!         count="5" />

This is a short description of the tags and attributes:

:config.interface:
  Optional. IP address and subnet of the component. If not set, the component
  requests and maintains the IP configuration via DHCP.

:config.gateway:
  Optional. IP address of the gateway of the IP subnet.

:config.dst_ip:
  Mandatory. IP address of the target host.

:config.period_sec:
  Optional. Length of send interval in seconds.

:config.verbose:
  Optional. Toggles wether the component shall log debugging information.

:config.count:
  Optional. After how many successful pings the component exits successfully.

:config.dst_port:
  Optional. Destination port resp. ICMP query ID to use.

:config.protocol:
  Optional. Protocol to ping with. Can be one of 'icmp', 'udp'.


Sessions
~~~~~~~~

This is an overview of the sessions required and provided by the
component apart from the environment sessions:

* Requires one Timer session.


Examples
~~~~~~~~

Examples of how to use the ping component can be found in the test scripts
'os/run/ping.run' and 'os/run/ping_nic_router.run'.
