Build Issues and Fixes

Faced compilation issues in Utopia and RdkWanmanager while triggering the broadband image build.
Reason for Fix: The removal of the WanFailOverSupportEnable distro in RPI was done to resolve compilation errors, as it appears that SKY (in the SKYHUB4 environment) may not have enabled, which causes inconsistencies in variable declarations in RPI4 build.

While performing sanity, faced the below issues and the mentioned the fix for the same:

  • Brlan0 is not getting the global IP.
  • Device is not updated as online in ACS server.
    • Erouter0 IP is not populated in given DM(Device.IP.Interface.1.IPv4Address.1.IPAddress) as lowerlayers is not updated properly.
  • Bound value is not updated in the mentioned DM(Device.DHCPv4.Client.1.DHCPStatus)
    • And server address also not updated.

Fixes for Sanity failures
