From 8873b174c7de6994fcfc1f4d53b1af08841607c4 Mon Sep 17 00:00:00 2001 From: Ye Ting Date: Fri, 18 Dec 2015 06:31:31 +0000 Subject: NetworkPkg: Update iSCSI driver to check existing AIP instances According to UEFI spec, iSCSI HBA must install an AIP instance with network boot information block. This patch updates UEFI iSCSI driver to check whether there are AIP instances installed by iSCSI HBA adapter and if yes, the UEFI iSCSI driver will return EFI_ABORTED in its driver binding Start(). Also the patch introduces a PCD PcdIScsiAIPNetworkBootPolicy for platform owner to define particular policy when the iSCSI HBA will survive and UEFI iSCSI will fail. The default policy is STOP_UEFI_ISCSI_IF_AIP_SUPPORT_OFFLOAD which means that when ISCSI HBA adapter installs an AIP and claims it supports an offload engine for iSCSI boot, the UEFI iSCSI driver will return EFI_ABORTED. The patch V2 adds a new value ALWAYS_USE_UEFI_ISCSI_AND_IGNORE_AIP to PCD PcdIScsiAIPNetworkBootPolicy. This allows the platform to avoid running into buggy IHV drivers that have issue with AIP. It is suggested by El-Haj-Mahmoud,Samer .
