We're seing a strange behaviour on some CE5 system.
Basically what we see it that TCPIP protocol refuses to bind
to any LAN card that comes up with media connected.
Only if the LAN driver delays link up indication few seconds
after init, TCPIP will stay bound to it.
Has anybody experienced this or have explanation?
Details: we can repro this with several drivers, including
the ne2000 sample driver from PB, and ne2000 pcmcia card.
The card is connected to a hub alone (no other devices) and
has static IP4 address assigned via WinCE control panel.
When the miniport starts, it gets a bunch of OID requests and
then few netbios packets to send. Shortly after sending these packets
out, TCPIP unbinds from the adapter.
But, when the miniport starts with media disconnected, and indicates
link up only after few seconds, TCPIP will stay bound.
