[dts] [PATCH] tests/vf_offload: correct case description and delete un-used function

[Tu, Lijuan]

1, The function checksum_enablesw is called by test_perf_checksum_throughtput.
2, found " --enable-rx-cksum " in testpmd start command line in set_up, that means enabled hardware checksum , the test_checksum_offload_disable actually tested hardware checksum, but we assume it tested software checksum.
