Functionally will be same, but what do you think about following,
to make easy to see what define adds:

+#define I40E_TX_OFFLOAD_MASK (		 \
+		PKT_TX_IP_CKSUM |	 \
+		PKT_TX_IPV4 |		 \
+		PKT_TX_IPV6 |		 \
+		PKT_TX_L4_MASK |	 \
+		PKT_TX_OUTER_IP_CKSUM |	 \
+		PKT_TX_OUTER_IPV4 |	 \
+		PKT_TX_OUTER_IPV6 |	 \

+#ifdef RTE_LIBRTE_IEEE1588
+		PKT_TX_IEEE1588_TMST |	 \
+#endif

+		PKT_TX_TCP_SEG |	 \
+		PKT_TX_QINQ_PKT |	 \
+		PKT_TX_VLAN_PKT |	 \
+		PKT_TX_TUNNEL_MASK)
  

Hi, Ferruh

As I know, the above change is incorrect in C code. We cannot use
#ifdef  #endif inside #define

Thanks
Jingjing

You can do:

#ifdef RTE_LIBRTE_IEEE1588
#define I40_TX_IEEE1588_TMST PKT_TX_IEEE1588_TMST
#else
#define I40_TX_IEEE1588_TMST 0
#endif

#define I40E_TX_OFFLOAD_MASK (   \
	I40_TX_IEEE1588_TMST |   \
	PKT_TX_IP_CKSUM |	 \
	...
