# v1.0 - 01/12/2001 - David Cashion - initial script
# v1.1 - 11/06/2002 - David Cashion - added ability to look at all interfaces
#                                     or just the one specified
# v1.2 - 09/30/2004 - David Cashion - updated to work with ce, ge, bge, dmfe
#                   - Scott Kampen    and added autoneg link partner check
#
# Polls the interfaces specified (or all of them with exception of loX)
# for speed, link, duplex, autonegotiation of link partner, and what its
# highest speed/duplex setting is.
