[ale] OT Linksys primiscuous mode

[linux at jtholmes.com (jtholmes)]

My Linux machine plugs directly into one of the four ports
on a Linksys WRT54G router and I can see any traffic to and
from my other machines. Which probably makes sense as
the router is not telling all ports what is coming and going
from each individual port.

Is there any way (short of putting a hub or switch in front
of the Linksys) to capture all packets going into and out of
the Linksys.
i.e. a promiscuous mode setting in the Linksys.

I have looked and can't find such an option.
