Packets for which\nRTE_MBUF_F_RX_IEEE1588_TMST and RTE_MBUF_F_TX_IEEE1588_TMST\nis not set, Rx and Tx timestamp should not be recorded.\n\nThis patch fixes this issue by checking if the required\nflags are set in the mbuf before recording timestamps.\n\nAlso this change defines separate values for\nDPAA2_TX_CONF_ENABLE and DPAA2_NO_PREFETCH_RX\n\nFixes: e806bf878c17 (\"net/dpaa2: support timestamp\")\nCc: stable@dpdk.org\n\nSigned-off-by: Vanshika Shukla <vanshika.shukla@nxp.com>\n---\n drivers/net/dpaa2/dpaa2_ethdev.h | 2 +-\n drivers/net/dpaa2/dpaa2_ptp.c | 8 ++++---\n
