I had reason to switch to using the RPi4B, which happens
to be booted from ACPI. The only Ethernet connection
present for this test is via:

For reference, the RPi4B's CortextA72 is speed controlled via:
over_voltage=3D6
arm_freq=3D2000
in the RPi4's config.txt . As stands UEFI is configured to
impose a 3 GiByte RAM limit to avoid FreeBSD not handling
it DMA address-range limitations yet.
My prior A72 test was on a MACCHIATObin Double Shot (where
EtherNet via USB3 is the only type of EtherNet available
in my context).
