I've responded inline below. Most of the functionality is already there if you use our driver from e1000.sf.net. We should have the updated network flow classifier interface added for the next release of the driver and we are currently hoping to make it into the 2.6.40-rc kernels for support in the in-kernel driver.

Currently it isn't that the features are in flux as much as the interface itself is in a state of flux. Specifically we are moving the interface over to network flow classifier from the current ntuple interface. The reason for this change is to address several issues we had with displaying filters. > Should I wait for the new filter approach or can I try it now? > Want to direct incoming multicast UDPv4 traffic to specific > queues by destination address.

The only limitation is that you will not be able to display the filters once you have entered them since there is currently a bug in the display function for ntuple filters within the kernel. > If it's reasonable to try it out now, which kernel would be best > to work with?

Any kernel 2.6.33 or later should support ntuple filters, however I would recommend using our latest ixgbe driver from e1000.sf.net as this addresses a number of issues which have been found in the ntuple filter functionality. However as I stated earlier the one limitation is that you will not be able to display the filters once they have been entered. > Thanks! > > David ------------------------------------------------------------------------------ What Every C/C++ and Fortran developer Should Know!
