bms 134bbb89c8 Fix a bug whereby the physical endpoints of a gre(4) tunnel would not ... be printed, if the module were loaded into a kernel which had INET6 enabled. The gre(4) driver does not use INET6, nor is it specified for IPv6. The tunnel_status() function in ifconfig(8) is somewhat overzealous and assumes that all tunnel interfaces speak KAME ifioctls. This fix follows the path of least resistance, by teaching gre(4) about the two KAME ifioctls concerned. PR: bin/56341		2003-11-14 20:58:00 +00:00
