If a GSO packet is sent to host that exceeds the limit (reported by NDIS), then the host is forced to do segmentation in software which has noticeable performance impact. The core rtnetlink infrastructure already has the messages and infrastructure to allow changing gso limits. With an updated iproute2 the following already works: # ip li set dev dummy0 gso_max_size 30000 These patches are about making it easier with veth. ==================== Signed-off-by: David S.
