Hello All,
I was trying to verify the feature "Allow SetData to clear configuration in Ip4Config2/Ip6Config Protocol" , But SetData returns with Write Protected Error Status
[Steps followed]
1. I've taken the above feature changes.
2. I've a UEFI test Application which call to SetData with DataSize is 0 and Data is NULL
Status = Ip4Cfg2->SetData (
Ip4Cfg2,
Ip4Config2DataTypeManualAddress,
0,
0
);
3. But SetData returns with Write Protected Error Status // Status = Write Protected
4. Faced the same error for setting Gateway &DnsServer
Guess the error is happening from
Thanks,
karunakar

If there are multiple DNS server address reported from DHCP server, it will like the Spec example: Dns(192.168.22.100, 192.168.22.101). Here, according your DNS Node, there is only one DNS server returned from DHCP.
