FreeBSD, eh -- as Stanley would say, welcome to the side of might and right.
Still, that's completely WEIRD, because Luca's measurements show Linux drops
a lot fewer packets than FreeBSD.
FC1 (RH9 for that matter) has NPTL (new POSIX thread library) - and are the
only major distros I'm aware of that have it - wonder if there's some
interaction between that and libpcap.
I can't imagine you are the only one seeing this, given the #s from
version.xml logs:
3328 debian
1604 redhat 9
923 fedora 1
487 redhat 8.0
Maybe it's unique to the specific NIC (I don't recall that we ever
identified which one you were using)... no, wait, you said "Intel 100Mbps
NIC".
Oh.
That bugger has some interesting history - there are TWO different drivers
in the Linux tree for it, because certain people don't play well with
others... didn't even think to have you try the other one. Both have
'issues', so it's not always a clear-cut decision. I seem to recall that
there are three or four different chipsets and the early ones have some
interesting bugs, which the drivers are SUPPOSED to work around. Maybe that
+ PC100 makes any timing issues worse...
Ah well, we'll never know...
Glad it's working for you.
