Fix regression detecting s390 CTC devices
Last modified: 2015-11-19 06:06:32 EST
Originally and on RHEL-7.1, we detected s390 CTC devices like: if (arptype == 256) { /* Some s390 CTC-type devices report 256 for the encapsulation type * for some reason, but we need to call them Ethernet. FIXME: use * something other than interface name to detect CTC here. */ if (g_str_has_prefix (ifname, "ctc")) return_type (NM_LINK_TYPE_ETHERNET, "ethernet"); } Bug 1212118 and upstream commit [1] implemented better device detection for s390 CTC devices. This was later broken entirely due to commit [2]. [1] http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=02c6a9334335d3ef32c6cc8fafc6cea235c80ffc [2] http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=ddaea22332907c05222cbec1e1b4365689fbda9f
This is fixed upstream: master: http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=8a6afe92c18dfefa91d057518be00b0127720fa5 nm-1-0: http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=2a8c93e940c3fdc5bb710f9fd1ec037e51524ed9 RHEL-7.1 would detect CTC devices based on the interface name. RHEL-7.2 would not detect them properly at all. This is a regression. Propose backporting the trivial fix.
