+Sets the RSS input transformation. Currently, only the
+.B symmetric-xor
+transformation is supported where the NIC XORs the L3 and/or L4 source and
+destination fields (as selected by
+.B --config-nfc rx-flow-hash
+) before passing them to the hash algorithm. The RSS hash function will
+then yield the same hash for the other flow direction where the source and
+destination fields are swapped (i.e. Symmetric RSS). Note that XORing the
+input parameters reduces the entropy of the input set and the hash algorithm
+could potentially be exploited. Switch off (default) by
