I think this will continue to work with older kernels after recompiling it. The change to the struct is backward-compatible since the new field is appended to the end and (from skimming over some of the code) it seems like other places handle this fine. The problem we encountered here is that the size we provided was smaller than expected.

Bug#829634: collectd: Please rebuild with linux-libc-dev >= 4.6
Package: collectd Version: 5.5.1-4 Severity: normal Hi, The size of the rtnl_link_stats64 structure changed in Linux 4.6 by commit 6e7333d315a768170a59ac771297ee0551bdddbf, which causes the netlink plugin to fail: Jul 4 22:14:28 host collectd[3022]: netlink plugin: link_filter_cb: IFLA_STATS64 mnl_attr_validate2 failed. Jul 4 22:14:28 host collectd[3022]: netlink plugin: ir_read: mnl_socket_recvfrom failed. Jul 4 22:14:28 host collectd[3022]: read-function of plugin `netlink' failed. Will suspend it for 120.000 seconds. Recompiling with headers from 4.6 should fix this (and would make the plugin fail with older kernels). The right fix would be to handle such structure extensions gracefully, but after a quick look, the libmnl library which the netlink plugin uses does not seem to have built-in support for that.
