If you want to go this route, make dhcp be the last argument not the
first one. If ifconfig understood dhcp (on my todo list) it would have
to be the last argument if you wanted it to work reliably because args
are processed in order and if your interface requires that you set the
media before it works, it's not going to work very well to run dhcp and
then fix the media. At least making dhcp be last insures that it will
continue to work once ifconfig grows dhcp support[*].

[*] No ifconfig will not contain any DHCP code, it will simply call a
script which calls your choice of dhcp clients. It's just lame that we
have variables that are supposidly ifconfig commands, but which won't
actually work.
