I haven't played with lagg on bce(4) so I definitely haven't tested this.
Can you dump the hardware statistics before/after the test=20
("sysctl -a | grep bce") and "diff" them to see which statistics have
changed?  Seems like it might be an RX filtering problem where the NIC
drops frames unexpectedly.  Does a trace on the GW show that if receives
the ICMP echo requests and sends out the responses?
