Hi,
First, thanks for the great work. JFFNMS is nice.
Second, following is a patch that will enable JFFNMS to work properly
with Dell Powerconnect Switches (at least tested with Powerconnect 3424).
No black magic here, the only problem with those switches is that they
always provide the same string ("Ethernet Interface") for the MIB
entries ifDescr. So, we simply detect if this is a Dell Switch and
indicate that the interface name is sored into the MIB entry ifName.
