[Winpcap-bugs] Unable to list devices for interfaces containing many IPv6 addresses

[Bhairav]

Hello,
I have captured debug information for an issue I am seeing according to the
bug page on the WinPcap page.  Here are the details as requested on the
page:

1) WinPcap version is 4.1 beta4.  Please note, I was seeing the issue with
4.0.2 previously and decided to try out this beta version before reporting
the problem.  The debug file created is with this beta version
2) The output of windump -D is blank (the debug file will make it clear why
this is the case)
3) Win2k3
4) 2 Network adapters installed - both HP NC324i PCIe Dual Port Gigabit
Server, but I think the issue is independent of the adapters themselves
5) The issue is this:  I have about 500 IPv4 and 500 IPv6 virtual addresses
on one (out of 2) interfaces.  At the application level (wireshark and
windump) I am not able to list the interfaces with these numbers of
addresses.  I could have 1000 IPv4 addresses without a problem (in listing
the interfaces) -- but whenever I get to a higher number of IPv6 (eg 1000
IPv4 + 14 IPv6), there becomes a problem listing the interfaces (a few IPv6
addresses is not a problem though). Looking at the debug file, I see the
following error:
[000005B4] 2008-10-18 16:34:23     The space in AdInfo->NNetworkAddresses is
not large enough, failing

Ideally, I wanted to use 1000 IPv4 + 1000 IPv6 addresses.  But, perhaps
winpcap is not able to get enough space for all the IPs?

Is it possible to increase the available storage space to accommodate these
numbers of IP addresses.

Thanks,
Bhairav
