I am running kernel 3.3.8 and trying to use batman adv ver 2017.4. I am getting error: net/batman-adv/hard-interface.c:101:28: error: 'const struct rtnl_link_ops' has no member named 'get_link_net' get_link_net is not part of rtnetlink.h in kernel v 3.3.8. Is 2017.4 not backwards compatible with older kernels per 4.0? get_link_net isnt added until kernel 4.0-rc1. I saw a previous message from 2016 saying: "Just to let everybody know: This patchset will break batman-adv compatibility for kernels older than 4.0 (see d37512a277dfb2cef8a578e25a3246f61399a55a):" Msg: https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2016-January/014306.html So was the backwards compatability broken intentionally so its no longer backwards compatible with older kernels? What can i do? -- Thanks Jorge
