those fragmented packets, will be sent to rxqueue0 by default? or RSS(you mean "filtering in IPv4"?) will calculate their hash value then determine the target rx-queue? Is it possible to do reassemble in ixgbe then pass through the flowdirector filter? ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
