Problems with 'any' device

["Lidwa, Eric (GSFC-582.0)[SGT]" <Eric.Lidwa-1 () nasa gov>]

This bug was introduced in the latest release of libpcap. I checked the version before 0.9.8 and the bug was not 
present.

It seems that in pcap-linux.c in activate_new the wrong socket is being created. Before the socket is created I set 
device variable to null if it is set to 'any' and that fixed the problem.

/* device should be set to NULL if 'any' */
if (strcmp(device, "any") == 0) 
    device = NULL;

I cannot submit the patch, could somebody please put the fix in.

Regards,
Eric

I have downlowaded the tar.gz files for libpcap version 1.0.0 and tcpdump version 4.0.0
After building it I have noticed that '-i any' no longer works. I get the following error when running it:

./tcpdump -i any
tcpdump: any: No such device exists
(SIOCGIFHWADDR: No such device)

The version which is installed on my fedora8 box

tcpdump version 3.9.7
libpcap version 0.9.7

works just fine with '-i any'

Has this been removed for some reason? Is it broken or am I missing something?
