Well, no idea - I just try and did not see this error on any system
here, checked on 9.2-STABLE/amd64 as well, all with minimal kernel
config (no network card in kernel, no SCSI adapter in kernel, no sound
card in kernel etc.) and every time if_gre kernel module was loaded
correctly when 'ifconfig gre0 create' command was issued in shell.
Maybe your ifconfig needs to be rebuilt if you have not build system
and binaries from the same sources, but no other idea here... Also, in
my sources I did not find 'device gre' in kernel either, so I am not
sure if this possibility even exists, but you can try it just to be
sure...
