It has been tested on two platforms (power and x86_64) and works very well. Apart from David Miller and Evgeniy Polaykov, we'd like to thank especially Andrew Gallatin for his great reviews and help to make that happen. After some discussion we decided to post the LRO patch separately from the driver patches. Our final driver patches for LRO will be posted later with some additional fixes for upstream inclusion to the netdev git. However, I'll also post our LRO patch for the driver today as an example of how to use this interface. Thanks a lot, Jan-Bernd [PATCH 1/1] lro: Generic Large Receive Offload for TCP traffic Changes to http://www.spinics.net/lists/netdev/msg37084.html 1) Fixed the LRO_MAX_PG_HLEN bug 2) skb->ip_summed can now be defined by driver for aggregated packets 3) The problem that the "ramp up" for tcp connections between machines with different MTU size (1500 vs 9000) is very slow has been fixed by setting skb->gso_size. 4) Checksum problem for little endian machines has been fixed 5) missing additon of vlan_hdr_len for TCP header determination has been added.
