Improve LXC network wait and gateway check logic
Some checks failed
Bump build.func Revision / bump-revision (push) Has been cancelled
Details

Browse Source 
Refactors the LXC container network initialization to simplify IP wait logic, reduce gateway ping attempts from 20 to 10, and provide clearer status messages. Now warns instead of failing if the gateway is unreachable but the container has an IP, improving robustness in network checks.
