Grrrr. You say you run tcpdump, yet you won't show us the packets
that tcpdump receives!!! Show _US_ the traffic, for crying out loud!
Do the packets actually have a destination address 00:05:5d:64:a7:de,
or do they have something else? If they _do_ have the right address,
have you tried doing 'ifconfig ste2 down; ifconfig ste2 up' to force
it to reprogram the RX filter? Have you tried the even simpler experiment
of just trying to change the MAC address on a single interface with
'ifconfig steX ether xx:xx:xx:xx:xx:xx' without even using the
fast etherchannel driver?
If you have not tried this, then try it now:
# ifconfig ste2 ether 0:0:e8:1:2:3
# ifconfig ste2 1.1.1.4 netmask 0xffffff00 up
# ping 1.1.1.3
