216 To turn it back on, one needs to set rx-flow-hash for tcp4/6 or udp4/6::
218 # ethtool -N fm1-mac9 rx-flow-hash udp4 sfdn
222 going to control the rx-flow-hashing for all protocols on that interface.

238 Please note that Rx hashing depends upon the rx-flow-hashing being on
239 for that interface - turning off rx-flow-hashing will also disable the
