Re: [Patch] NetworkPkg/IScsiDxe: Display InitiatorInfo in attempt page even DHCP enabled.

["Wu, Jiaxin" <jiaxin.wu@intel.com>]

Hi Karunakar,

Thanks the verification, I agree it's another iSCSI bug that exposed by this patch. 

In IScsiGetConfigData() function, The existing attempt will always trigger the DHCP process if Initiator DHCP enabled no matter it associates with the current NIC or not. That's incorrect and unreasonable as you overserved if we display the InitiatorInfo in attempt page.

I will send another separated but series patch to fix this issue.

Thanks,
Jiaxin
