Which issue(s) this PR fixes:

Virtual interfaces, such as bond/vlan, may be deleted and recreated by NetworkManager. A newly created virtual interface has a new DBus object path.

This patch fixes NetworkManager syncer for virtual interfaces by using the device name instead of the DBus object path.

WHAT

🤖 Generated by Copilot at a80f6b8

Refactored and optimized the networkManagerSyncer code in pkg/daemon/nm_linux.go to use IP interface names instead of dbus object paths. This simplifies the device identification and processing logic and improves the event handling and device management performance and reliability.

Sing, O Muse, of the skillful coder who simplified
The networkManagerSyncer code, and by his wisdom applied
The names of IP interfaces, not the paths of dbus objects
To identify and process devices, and avoid defects.

• Simplify the networkManagerSyncer struct and its methods by using IP interface names instead of dbus object paths for the devices (link, link, link, link, link, link)
• Modify the Run function to use strings.HasSuffix to check the event name and to filter out irrelevant devices from the workqueue (link, link)
• Move the bridgeMap lookup outside the lock in the ProcessNextItem function to improve performance (link)
