Subject: Regarding PXE boot NACK error.

Hi All,
When one of DHCP cum PXE server which is not configured properly and returns NACK.
When PxeBcDhcp4Dora() returns EFI_TIME_OUT and PxeBcSelectBootPrompt () returns EFI_NOT_FOUND, do we need to abort the DHCP transaction or not in PxeBcDiscoverBootFile()? Or should we retry?
Currently it calls PxeBcDhcp4BootInfo() to get the boot info.
PxeBcDhcp4CallBack is getting called 2 times:
Dhcp4Event: 0x1 (Dhcp4RcvdOffer)
Dhcp4Event: 0xC (Dhcp4Fail)
Do we need to retry PxeBcDhcp4CallBack() for more times even if it is Dhcp4Fail?
EfiPxeLoadFile() -> PxeBcLoadBootFile () -> PxeBcDiscoverBootFile() -> PxeBcSelectBootPrompt()
Attached the transaction debug log for reference.
Please share your comments.
Thank you,
Younas.
