The issue is that the list of flags in the application has to be synchronized with the flags defined in rte_mbuf.h. This patch introduces 2 new functions rte_get_rx_ol_flag_name() and rte_get_tx_ol_flag_name() that returns the name of a flag from its mask. It also fixes rxonly.c to use this new functions and to display the proper flags.
