Commit 7182f8f8 authored by Anthony Foiani's avatar Anthony Foiani Committed by Greg Kroah-Hartman

staging: usbip: set usbipd server port via "-t" / "--tcp-port" option.

Add an option "-t" / "--tcp-port" to specify the TCP port to listen
on.  Downcase associated variables as they're no longer constants.
