In commit b396966c4 (netfilter: xt_TCPMSS: Fix missing fragmentation handling), I attempted to add safe fragment handling to xt_TCPMSS. However, Andy Padavan of Project N56U correctly points out that returning XT_CONTINUE in this function does not work. The callers (tcpmss_tg[46]) expect to receive a value of 0 in order to return XT_CONTINUE. Signed-off-by: Phil Oester <kernel@linuxace.com>
