Thanks.  How does one set/query the roaming mode, I can't find any
mention of it in the iwconfig man page.  And is there a roaming mode

Does this mean that the card will re-associate with another AP in an
ESS when the signal quality gets too low?  I'd always assumed none of
this stuff was implemented in Linux yet, since I'd not seen it
documented anywhere (and since everyone seems to have a preoccupation
with explicitly setting channels).
