There could be a couple of possible issues.

First, what kernel are you using?  You need to be using a 2.6.30 or
later kernel to support ntuple filtering.

Second, have you enabled ntuple filtering for the port you are using? 
The FdirMode parameter is a comma separated value.  If you specify
FdirMode=2, but have 2 ports, the second port will not be enabled.  To
enable it for 2 ports you would need to specify FdirMode=2,2.  You can
also verify that ntuple filtering is enabled by running "ethtool -k eth2".

Finally, what version of ethtool are you using?  You can verify it via
either "ethtool --version", or the version should be the first line of
"ethtool -h". In order to support ntuple filters you need to be using
version 2.6.39 of ethtool, otherwise unsupported commands are used.
