Subject: [edk2] [Patch] NetworkPkg: Record user configured TargetIP/Port in iBFT
Current ISCSI driver records redirected iSCSI targetIP/Port in iBFT once redirection occurs, which removes the possibility of the OS to reconnect to the configured IP for load balancing. The behavior is not explicitly described in IBFT spec, though the MSFT expert confirm we should record original user setting rather than publish the redirected IP.

Subject: [Patch] NetworkPkg: Record user configured TargetIP/Port in iBFT
Current ISCSI driver records redirected iSCSI targetIP/Port in iBFT once redirection occurs, which removes the possibility of the OS to reconnect to the configured IP for load balancing. The behavior is not explicitly described in IBFT spec, though the MSFT expert confirm we should record original user setting rather than publish the redirected IP.
Thanks Sriram for reviewing and validating this patch in his test-bed.
