The network interface configuration is taking some delay to update in DHCP case

[Karunakar P <karunakarp@amiindia.co.in>]

Hi All,

  I've been facing an issue with IP4 SERVICE Default interface value.



[Reproduction Steps]
1.Add trace messages to print the values of ip and SubnetMask in Ip4FormExtractConfig() -> Ip4Config2ConvertConfigNvDataToIfrNvData()

EFI_STATUS
Ip4Config2ConvertConfigNvDataToIfrNvData (
IN     IP4_CONFIG2_INSTANCE       *Instance,
IN OUT IP4_CONFIG2_IFR_NVDATA     *IfrNvData
)
{
...
IpSb = IP4_SERVICE_FROM_IP4_CONFIG2_INSTANCE (Instance);

+ Print value of IpSb->DefaultInterface->Ip
+ Print value of IpSb->DefaultInterface->SubnetMask

...
}
2. Assign ip to SUT using IPv4 Network Configuration page.
   ( Enable Configured and Enable DHCP and Save Changes and Exit )
3. reset the SUT once IP assigns

[Observation]

1.       On restart, Ip4FormExtractConfig() gets call and prints Ip and SubnetMask values are 0.

2.       If add some delay before printing those values , then getting the proper values
                                +  add Delay some delay
+ Print value of IpSb->DefaultInterface->Ip

+ Print value of IpSb->DefaultInterface->SubnetMask

3.       In the case of Static Ip , printing proper values without giving any delay.


Could you please help in where it is taking time to update the values in DHCP case.

Thanks,
Karunakar.
