Change nic configuration at runtime?   
Is it possible to change the nic parameters like speed,duplex at run time? if yes what utility can i use to change these
 things?

RE: Change nic configuration at runtime?   
If this is for 6.3.2, then the only way is to restart the driver with
the speed and duplex command line options. I cannot comment on the 6.4
drivers.

Actually 6.4 does have support to change the
speed, duplex etc during runtime.  See the
ifconfig utility - the mediaopt option.

Note that only native 6.4 drivers, and bsd
drivers, support this API - see bsd_media.c
in the source - to get and set the media options.

If you are running a 6.3 (io-net) driver
with the shim, since the underlying driver
does not support the changing of speed and
duplex during runtime, neither does the shim.

Andrew,
           I will look into bsd_media.c.Thanks.

Hugh, 
        If i need to change configurations at runtime for io-net drivers can i implement those config changes as 
devctls().I beleive there is no change in ifconfig utility between 6.3.2 and 6.4.

Hugh,
        sorry for that stupid question about ifconfig across 6.3.2 and 6.4.0.I believe there should be lot of 
differences internally.Lets say iam writing my own utility can i use devctls() from it to control speed and duplex 
parameter.

Yes, you can do this, but the driver will have to be re-started to
implement the changes, unless you change the driver architecture.

Well I don't see the mediaopts under the 6.3.2 version of ifconfig, so I
don't think that this is possible under 6.3.2.
