Please describe the problem:
On FreeBSD SIOCGIFFLAGS yields ENXIO for non-IP/non-configured interfaces. GDM (gdmchooser) prints a warning at level CRITICAL to the log, making the user think that there's a problem.

Steps to reproduce:
1. Run XDMCP browser on FreeBSD 7


Actual results:
Syslog shows e.g.:
Jul 25 19:52:31 pc139 gdmchooser[2547]: CRITICAL: Could not get SIOCGIFFLAGS for ^\b
Jul 25 19:52:31 pc139 gdmchooser[2547]: CRITICAL: Could not get SIOCGIFFLAGS for 8^R^C



Expected results:
no warnings in syslog

Does this happen every time?
yes

Other information:
The corresponding ioctl-call should fail silently. Nothing to see here, please move along (why not also print strerror(errno) while we are here?):
