You shouldnt have to. However there are cases where it might have run
(system shutdown or errors).

There are kernel and library changes between the two. I have had
problems with a broadcom working in FedCore 3 and not in FedCore 4
because of this.

Never underestimate the stupidity of drivers or switches. I have had
to toggle as many gigE to gigE ports on switches as I have had with
100mbit. Some of them were problems with the network drivers.. some
with bios problems with machines, and some with changes in the switch.
The box would show crap problems and it was because it had
re-negotiated to 100mbit  half (this is with copper.. fibre is a
different matter).

Heck I had one problem that turned out to be a bad cable. Worked great
with an older version of Fed and then an upgrade started giving me
crap. We put the cable through a tester and found it had a miniscule
break half-way through. Why it worked before so great.. no idea.
