Hi Ye,
I got the SnpNt32Dxe.dll built from given source code & WinPCAP library as
mentioned in the UEFI Network Stack Getting Started Guide(pdf)
<http://sourceforge.net/projects/network-io/files/Documents/EFINetworkStackGettingStarted.pdf/download>.
And copied the dll in appropriate location.
Now when I am loading SnapNt32Dxe.efi, I get "Already started". So looks
like something has worked. Earlier I was getting "Not found" error.
But even then ifconfig command failing.
ifconfig: Locate protocol error - 'Ip4Config protocol'
TCP4dxe, ARPdxe, Dhcp4Dxe, MnpDxe all are loaded.
SystemTable->BootServices->LocateHandleBuffer (
ByProtocol,
&gEfiTcp4ServiceBindingProtocolGuid,
NULL,
&HandleCount,
&Handles
);
call is still failing.
Thanks.
