This patch adds an IAVF testpmd command "set tx lldp on" which
will register an mbuf dynfield IAVF_TX_LLDP_DYNFIELD to indicate
the need to test transmit LLDP packet.
It needs to stop and restart Tx port to select correct Tx path.

+Register mbuf dynfield to test Tx LLDP
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Register an mbuf dynfield IAVF_TX_LLDP_DYNFIELD on dev_start to indicate
+the need to send LLDP packet, this dynfield needs to be set to 1 when
+preparing packet.
+
+For dpdk-testpmd application, it needs to stop and restart Tx port
+to take effect.
+
+Usage::
+
+ testpmd>set tx lldp on
