  In DPDK, the macros RTE_BE32 or RTE_BE16 are usually used for
constant values. And functions such as rte_cpu_to_be_32 or
rte_cpu_to_be_16 are optimized for variables.

Indeed your change is in the correct files and I agree that it's need to be done,
But you are not doing it for all RTE_BE32 and RTE_BE16 in the app or the same files

After quick search I see:
app/test-flow-perf/items_gen.c:12
app/test-flow-perf/actions_gen.c:29

While you are doing the change only for:
app/test-flow-perf/items_gen.c:1
app/test-flow-perf/actions_gen.c:14

Can you please extend your fix for all needed vars.

BRs,

HI,
  I see all the other RTE_BE32 and RTE_BE16 are used for constant
values. I think it is not necessary to fix them:

In app/test-flow-perf/items_gen.c:
.hdr.vlan_tci = RTE_BE16(VLAN_VALUE),
.hdr.vlan_tci = RTE_BE16(0xffff),
ipv4_masks[ti].hdr.src_addr = RTE_BE32(0xffffffff);
.protocol = RTE_BE16(RTE_ETHER_TYPE_TEB),
.protocol = RTE_BE16(0xffff),
.hdr.teid = RTE_BE32(TEID_VALUE),
.hdr.teid = RTE_BE32(0xffffffff),
.data = RTE_BE32(META_DATA),
.data = RTE_BE32(0xffffffff),
.data = RTE_BE32(META_DATA),
.data = RTE_BE32(0xffffffff),

In app/test-flow-perf/actions_gen.c:
.data = RTE_BE32(META_DATA),
.mask = RTE_BE32(0xffffffff),
.data = RTE_BE32(META_DATA),
.mask = RTE_BE32(0xffffffff),
eth_hdr.ether_type = RTE_BE16(RTE_ETHER_TYPE_VLAN);
eth_hdr.ether_type = RTE_BE16(RTE_ETHER_TYPE_IPV4);
eth_hdr.ether_type = RTE_BE16(RTE_ETHER_TYPE_IPV6);
vlan_hdr.eth_proto = RTE_BE16(RTE_ETHER_TYPE_IPV4);
vlan_hdr.eth_proto = RTE_BE16(RTE_ETHER_TYPE_IPV6);
udp_hdr.dst_port = RTE_BE16(RTE_VXLAN_DEFAULT_PORT);
udp_hdr.dst_port = RTE_BE16(RTE_VXLAN_GPE_UDP_PORT);
udp_hdr.dst_port = RTE_BE16(RTE_GENEVE_UDP_PORT);
udp_hdr.dst_port = RTE_BE16(RTE_GTPU_UDP_PORT);
gre_hdr.proto = RTE_BE16(RTE_ETHER_TYPE_TEB);
item_udp.hdr.dst_port = RTE_BE16(RTE_VXLAN_DEFAULT_PORT);
