First off, please let me know if this list isn't an appropriate place for these sorts of questions. With that out of the way, I'm trying to understand the sample program at: http://git.netfilter.org/libmnl/tree/examples/rtnl/rtnl-link-dump.c I've been able to puzzle most of it out, but I'm confused by the use of the struct rtgenmsg (declared on line 88 and used on lines 95-96). * Based on rtnetlink(7), shouldn't this more properly be a struct ifinfomsg (even though only rtgen_family/ifi_family is set)? * More importantly, why is setting this to AF_PACKET required at all? Testing the program without setting it reveals that it definitely is required, but I haven't been able to find anything that explains *why* that is the case.
