Update metainfo to exclude loopback app from xsoftip browser
Refactor to eliminate warning in 13 tools.

  The ethernet_tx_server code performed a transaction on an array member.
  In the 13 tools this will warn unless the array member is only accessed
  one in the first statement of the transaction. This is fixed by
  outlining the code to a transaction function.
Moved documentation to more standard dir.
