      Is there somewhere a page that lists NICs/drivers that have issues with hardware offloading of TCP segmentation and large receive?

      The text there just says:

      Disable hardware TCP segmentation offload

      Checking this option will disable hardware TCP segmentation offloading (TSO, TSO4, TSO6). This offloading is broken in some hardware drivers, and may impact performance with some specific NICs.

      Disable hardware large receive offload

      Checking this option will disable hardware large receive offloading (LRO). This offloading is broken in some hardware drivers, and may impact performance with some specific NICs..

      but I'd not have the faintest idea where to look up which NICs do require these to be selected, and which would benefit by having this functionality enabled.
