Check if Class3 connection is available and if yes setup all data.

This function can be called after all data has been parsed from the forward open request

Parameters

connection_object	pointer to the connection object structure holding the parsed data from the forward open request
extended_error	the extended error code in case an error happened

Returns

general status on the establishment

• kEipStatusOk ... on success
• On an error the general status code to be put into the response
