That's odd - I'd expect it to have been the other way around (because,
if the driver sometimes doesn't supply outgoing packets, I'd expect it
to supply them only if you're in promiscuous mode).

Perhaps the driver doesn't actually support promiscuous mode, and won't
put the card into a mode where it listens for packets not sent to it.

You'd have to ask the supplier of the driver (Dell, or whoever supplied
it to them) what it does (ask them what happens if the "filter" for the
card is set to NDIS_PACKET_TYPE_ALL_LOCAL, which is what WinPcap sets it
to in non-promiscuous mode, and what happens if it's set to
NDIS_PACKET_TYPE_PROMISCUOUS, which is what WinPcap sets it to in
promiscuous mode).
