From 0a1ec676ddbee712e1c1da679be4bdc529caf215 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 20 Mar 2006 21:23:59 -0800 Subject: [PATCH] [DCCP]: Dont use dccp_v4_checksum in dccp_make_response dccp_make_response is shared by ipv4/6 and the ipv6 code was recalculating the checksum, not good, so move the dccp_v4_checksum call to dccp_v4_send_response.
