Do I miss anything here ? In addition, the GRO SKB needs to be setup properly. For example, the gso_type, gso_size, gso_segs, CHECKSUM_PARTIAL, etc, all have to be setup. Hardware needs to provide all the necessary information to set this up. In case this GRO SKB is re-routed to an output device, TSO or GSO needs to be performed on the packet and the original packet stream should be re-constituted exactly.
