This usage of TSO support is called Enhanced Drivers Packing , means a better usage of our send buffers and thus less IO operations. The other option is the "real" TCP segmentation offload support driven by hardware. The code is in qeth_tso.[hc] .... > > If that's beneficial, that's fine, but such a thing belongs somewhere > generic so that other drivers can do it without %100 replicating your > qeth code. I don't think that it is something for generic usage as it is very OSA card specific and qeth driver respectively. > - > : send the line "unsubscribe linux-net" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
