I was looking at the netstats for my firewall/NAT box, and noticed
that it shows the following:

Name  Mtu   Network       Address            Ipkts Ierrs    Opkts Oerrs  Coll
pn0   1500  <Link>      00.a0.cc.39.93.a9  1821536  1725  1349529  2072     0
pn0   1500  c2-128.xtlab. www              1821536  1725  1349529  2072     0
pn1   1500  <Link>      00.a0.cc.3a.59.fc  1434045     0  1855611 167620     0
pn1   1500  tyan/24       router.zuhause.  1434045     0  1855611 167620     0

pn0 is connected to the DSL modem, and pn1 is connected to a switching
hub, and is configured for 100 baseTX full duplex and is connected to
a 10/100 switching ethernet hub.  This is saying over 9% of the
packets sent have errors!  What should I look at to determine exactly
what is causing these errors?  The switch indicates that all of my
NICs are 100 baseTX full duplex, and I know they're configured that
way.  I don't see any input errors on the other FreeBSD boxes
connected to the switch.  I also have a Windows 98 box connected to
the switch, but if there's any way to detect ethernet media errors
with it, I'm not aware of it.
