From af4afdc0e0482fd6f4d6d8da77df30527b75e421 Mon Sep 17 00:00:00 2001 From: Ayush Ranjan Date: Fri, 11 Dec 2020 10:32:03 -0800 Subject: [netstack] Decouple tcpip.ControlMessages from the IP control messges. tcpip.ControlMessages can not contain Linux specific structures which makes it painful to convert back and forth from Linux to tcpip back to Linux when passing around control messages in hostinet and raw sockets. Now we convert to the Linux version of the control message as soon as we are out of tcpip.
