dc0 collisions in -current

I haven't read the thread in question through completely, but I just want
to make you guys aware that -current's if_dc has a bug where it will
report _false_ collisions on many network cards.

Example from one of my systems:

dc0    1500 <Link#2>      00:20:78:0f:a0:a6 10307782     0 15428017     0 827213
dc0    1500 10.1.1/24     10.1.1.6          10304908     - 15428012     -     -

However, I am not aware of it producing any output error messages, so that
may be a real problem.

Also, "dc0: TX underrun -- increasing TX threshold" is normal, you will
see that message a few times once you start putting the system under
network load until it finds a good TX threshold.  Nothing to worry about
there.

So, as I said, I did not read the entire thread, so I'm not sure if a real
problem is occuring for you guys or not; just make sure that you aren't
chasing a ghost.
