Introduces two changes into l3fwd-acl behaviour to make
it behave in the same way as l3fwd:
 - Add a command-line parameter to allow the user to specify the
   destination mac address for each ethernet port used.
 - While forwarding the packet update source and destination mac
   addresses.

Replace '--scalar' command-line option with new one: --alg=<algname>
to allow user explicitly select desired classify method.
This is an optional parameter, if not specified default classify
algorithm will be used.

  To: dev; +Cc: Konstantin Ananyev

Introduces two changes into l3fwd-acl behaviour to make
it behave in the same way as l3fwd:
 - Add a command-line parameter to allow the user to specify the
   destination mac address for each ethernet port used.
 - While forwarding the packet update source and destination mac
   addresses.

Replace '--scalar' command-line option with new one: --alg=<algname>
to allow user explicitly select desired classify method.
This is an optional parameter, if not specified default classify
algorithm will be used.
