From 6853f21f764b04e58df5e44629fec1fb8f3cbf2e Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Wed, 28 Feb 2018 23:29:29 +0200 Subject: ipmr,ipmr6: Define a uniform vif_device The two implementations have almost identical structures - vif_device and mif_device. As a step toward uniforming the mr_tables, eliminate the mif_device and relocate the vif_device definition into a new common header file. Also, introduce a common initializing function for setting most of the vif_device fields in a new common source file. This requires modifying the ipv{4,6] Kconfig and ipv4 makefile as we're introducing a new common config option - CONFIG_IP_MROUTE_COMMON.
