From a430a43d087545c96542ee64573237919109d370 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 8 Jul 2006 13:34:56 -0700 Subject: [NET] gso: Fix up GSO packets with broken checksums Certain subsystems in the stack (e.g., netfilter) can break the partial checksum on GSO packets. Until they're fixed, this patch allows this to work by recomputing the partial checksums through the GSO mechanism. Once they've all been converted to update the partial checksum instead of clearing it, this workaround can be removed. Signed-off-by: Herbert Xu Signed-off-by: David S.
