+Subject: [PATCH] infiniband: restore detection of Ipoib iface type
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Fixes 5e13d3f "Prefer LinkInfo::Kind as interface type". This commit
+made to always prefer InfoKind over anything for Ethernet, but at the
+same time it made to prefer LinkLayerType over InfoKind for Infiniband.
+This causes that the Ipoib iface typeis not detected anymore, causing
+two problems:
+- Interfaces previously detected as Ipoib are now detected as
+  Infiniband, breaking some clients like nmstate.
+- The Ipoib data is not parsed, as it is only done for Ipoib iface type.
+
+Fix it by prefering the "Infiniband" generic type only if no InfoKind
+was detected, or InfoKind::Other was detected.
