capability
• The left side is termed "Transmit Interfaces" as the interfaces
are driven by the DMA transmit interfaces in pass-through
mode. If the switch is enabled, these interfaces connect to the
switch internal receive interfaces. The right side is named
"Receive Interfaces" as the interfaces represent (are driven
from) the respective MAC receive interfaces in pass-through
