Author: glebius Date: Thu Feb 19 22:35:23 2015 New Revision: 279026 URL: https://svnweb.freebsd.org/changeset/base/279026 Log: - Rename 'struct igmp_ifinfo' into 'struct igmp_ifsoftc', since it really represents a context. - Preserve name 'struct igmp_ifinfo' for a new structure, that will be stable API between userland and kernel. - Make sysctl_igmp_ifinfo() return the new 'struct igmp_ifinfo', instead of old one, which had a bunch of internal kernel structures in it. - Move all above declarations from in_var.h to igmp_var.h, since they are private to IGMP code.
