Edgerouter ER-X: can eth0 be put back on the hardware switch?

Confirming bridger works to reduce CPU usage. Test system: ER-X configured as switch with eth0 through eth4 bridged to br-lan. Hardware flow offloading enabled. When I do a file copy between between any of the ports eth1-4, there is no CPU usage when monitored by Realtime Graphs. On the other hand, a file copy involving eth0 results in significant CPU usage. After installing bridger, a file copy involving eth0 also has no CPU usage. Now my contention is who cares that there is a big CPU load…
