[LU-14954] socklnd: fix link state detection

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.15.0
• Severity: 3
• Epic Link: Socklnd Improvements
• Assignee: Serguei Smirnov

Description

Due to matching only the device index, link detection implemented in LU-14742 has issues with confusing the link events for the virtual interfaces with the link events for the interface that LNet was actually configured to use. Fix this by improving the identification of the event source: use device name in addition to device index. Additionally, to make sure the link fatal state is cleared only when the device is bound to the IP address used at NI creation, subscribe to inetaddr events in addition to the netdev events.
