changed the parameters. but this is only applicable for hme
or nge interfaces for interfaces like e1000g0 ,g1.. the
process is different, I m mentioning the process in the
second stage.

for e1000g0, e1000g1 ...

we need to change the parameters in the kernal drivers
#cd /kernel/drv

#vi e1000g0 , you will see all the possible options to for
full and half duplex. just change the values and save the file.
