/* * Create the "control" list for this pcb. * * The routine will be called from upper layer handlers like tcp6_input(). * Thus the routine assumes that the caller (tcp6_input) have already * called IP6_EXTHDR_CHECK() and all the extension headers are located in the * very first mbuf on the mbuf chain. * We may want to add some infinite loop prevention or sanity checks for safety. * (This applies only when you are using KAME mbuf chain restriction, i.e. * you are using IP6_EXTHDR_CHECK() not m_pulldown()) */
