BBS is *technically* part of the PnP BIOS specification, so doesn't

used by some implementations to describe uefi boot attempt order.
I may have used the wrong term but SMC Bioses, in full UEFI mode still
mention UEFI BBS Network Priorities for instance.
ipxe.efi last I recall does not really pay attention to 'what device
executed me?' because the overall design is "I am probably being
executed from a chip on a nic or from a usb mass storage device". Not
really focused on chainloading.
Got it: indeed ipxe.org states
"ipxe all native drivers, commonly used for usb based boot media or
where iPXE is not used in a chainloaded manner."
hence both the "full" init (no chainloading) and all nics init.
Thanks again (sorry for the slow catching up ;-))
