Description Flags
Add support for ctc devices so that anaconda can install from those none

Description Karsten Hopp 2010-10-11 17:44:17 UTC 
Description of problem:
Installation via CTC devices is currently not possible. 
First problem is that NM doesn't mark those devices as Network devices.
In src/nm-udev-manager.c:net_add the content of p.e. 
/sys/devices/ctcm/0.0.0150/net/ctc0/type is read. As it is a pointopoint device it doesn't have '1' in it but '256', so the check for 'if ((etype != 1)' fails.

Second problem that I couldn't pin down yet is that nm_connection_verify in the wired_connection_from_ifcfg function fails and afterward the ctc0 network interface gets shut down.

This is currently blocking installations with the current NM on the hercules  s390x emulatory, which would be very helpful for other Fedora maintainers to track down bugs in their packages as most of them don't have access to a real mainframe.

I wasn't sure how to detect a network interface is of type CTC, so I'm currently relying on the interface name.

Patches and additional testcases committed upstream as:

Dan, does that mean that the fixes will appear in F-15 GA (or better post-Beta) NetworkManager?

I believe that is correct, yes.
