What I have done in the past is use the mii-tool.  You will need to do a
man mii-tool to see all the options.  the mii-tool is "supposed" to
detect your speed and duplex, but most of the time I have to do a
"mii-tool -F 100baseTx-FD" notice the -F forces the connection.  First I
would do a mii-tool -r to try to reset the autonegotiation.
