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 <samer.el-haj-mahmoud@hpe.com>.
