long delay for scan results after suspend


With the new OLPC XO-1.5, our kernel driver fully powers down the
wireless device during suspend to the point where the kernel thinks the
SDIO card has been ejected.

It immediately comes back on resume, but there is a delay of
approximately 20 seconds before NM offers scan results to Sugar, which
is frustratingly long.

When is NM expected to perform scans in this situation?

It is possible that the libertas wifi driver is taking this long to
deliver results although it seems unlikely.
