From 1d997f1013079c05b642c739901e3584a3ae558d Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Fri, 28 Oct 2022 04:42:21 -0400 Subject: rtnetlink: pass netlink message header and portid to rtnl_configure_link() This patch pass netlink message header and portid to rtnl_configure_link() All the functions in this call chain need to add the parameters so we can use them in the last call rtnl_notify(), and notify the userspace about the new link info if NLM_F_ECHO flag is set. - rtnl_configure_link() - __dev_notify_flags() - rtmsg_ifinfo() - rtmsg_ifinfo_event() - rtmsg_ifinfo_build_skb() - rtmsg_ifinfo_send() - rtnl_notify() Also move __dev_notify_flags() declaration to net/core/dev.h, as Jakub suggested.
