Documentation for 10G cards and other drivers suggest enabling rxcsum for RSS and disabling otherwise. When PCSD bit is not set then fragment checksum and IP identification are reported in the rx descriptor. When PCSD bit is set then RSS hash value is reported in the rx descriptor. RSS and RX IPP checksum are mutually exclusive.
