Hi Dave: [NET] gso: Fix GSO feature mask in sk_setup_caps
This isn't a bug just yet as only TCP uses sk_setup_caps for GSO. However, if and when UDP or something else starts using it this is likely to cause a problem if we forget to add software emulation for it at the same time. The problem is that right now we translate GSO emulation to the bitmask NETIF_F_GSO_MASK, which includes every protocol, even ones that we cannot emulate. This patch makes it provide only the ones that we can emulate.
