From 4fcd6b991685493185c2bb8a76b21aadb658bd76 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 31 May 2007 22:15:50 -0700 Subject: [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. Signed-off-by: Herbert Xu Signed-off-by: David S.
