[c-nsp] System MTU on 4948

[Jeffrey Denton]

If the documentation is correct, then the answer should be no.  YMMV

In the "Catalyst 3560 Switch Software Configuration Guide Cisco IOS
Release 12.2(46)SE", page 10-29:

"If you change the system MTU size to a value smaller than the
currently configured routing MTU size, the configuration change is
accepted, but not applied until the next switch reset."

In the "Catalyst 4500 Series Switch Cisco IOS Software Configuration
Guide Release 12.2(46)SG" (Cisco's website mentions "Catalyst 4900 and
4500 switches share configuration information"), I didn't see the same
warning.  See page 24-5 on System MTU.  Pages 6-20 and 6-21 discuss
MTU and Jumbo Frame support.  Page 29-8 discusses configuring IP MTU
sizes on layer 3 interfaces.
