[dts][PATCH V1 03/12] tests/checksum_offload: update dts code for dpdk csum change

[Weiyuan Li]

According to dpdk commit 9b4ea7ae77fa(app/testpmd: revert MAC update in checksum forwarding) modify
the script adapt to this chagne.

1. Modify VF case to enable promisc.
2. Modify PF case to send packet dst mac is random.
