Hi.  First of all, great job with the MP support.  It's nice to be able to
use winpcap on my MP machine.  Now, the bugs...

Win2K throws a BSOD when I attempt to send a packet flood using winpcap's
native API (not the libpcap wrappers).  The BSOD error says
MULTIPLE_IRP_REQUESTS.  To send the packet flood, I used PacketSetNumWrites
() to set the iteration to ~10000 and then called PacketSendPacket() to
send the buffer (buffer<=64bytes).  I then put the PacketSendPacket() code
in a tight infinite loop.

WinXP (on the same machine via a disk image) seems to prevent my app from
starting at all.  After a few tries, though, the app can get started but
then it BSODs with just the STOP code.  I couldn't see any error
information.

Test machine environment:
Win2KPro, WinXPPro
Dual P3-500 MHz
384 MB RAM
3Com EtherLink XL 10/100 PCI TX (3C905B-TX) network driver.

I was also able to generate debug logs using DebugView
(www.sysinternals.com) and crash dumps (less portable I imagine).  I didn't
know whether to post bugs here or send it to the NTOP guys, so I just sent
it to everybody.  If there's a specific group that I should send future
bugs to, please let me know.

Dear all,
we (Michel Montague and me) have just released a patch for running
Winpcap 3.X on multiprocessor (MP) machines. This patch allows users to
run winpcap-based applications such as ntop, nProbe, Ethereal and snort
on MP machines under Windows.

For more information about this topic please visit
http://www.ntop.org/winpcap.html. We have tested the patch on Win2K.
Please report us about other Windows versions.

Have a lot of fun, Luca & Michel
