I don't think that's an option. The CPU is dimensioned for switch
management. For the RTL838x, using the current ethernet driver, it tends
to break down completely at 30-40 Mbits/s.
Multicast offloading is necessary to be able to use one of these devices
for e.g IPTV. Which definitely is a relevant use case.
