This patch adds an IAVF testpmd command "set tx lldp on|off" which
will register an mbuf dynfield IAVF_TX_LLDP_DYNFIELD to indicate
the need to send LLDP packet.
It needs to close the Tx port first, then "set tx lldp on", and reopen
the port to select correct Tx path, only supports turning on for now.
