commit bf988435bd upstream.
struct ethtool_rxnfc was originally defined in 2.6.27 for the
ETHTOOL_{G,S}RXFH command with only the cmd, flow_type and data
fields. It was then extended in 2.6.30 to support various additional
commands. These commands should have been defined to use a new
structure, but it is too late to change that now.
Since user-space may still be using the old structure definition
for the ETHTOOL_{G,S}RXFH commands, and since they do not need the
additional fields, only copy the originally defined fields to and
from user-space.
