freebsd-dev/usr.sbin/fwcontrol/fwcontrol.c
Sean Bruno 7f1b527c00 Beginning of overhaul of fwcontrol:
-  Documentation of send_phy_config()
-  cleanup of malloc's() and added error checking throughout
-  new capability to iterate over multiple firewire buses
-  update usage() display
-  cleanup command line parsing to allow out of order switches
-  cleanup command line parsing to allow multiple switches per invocation
-  cleanup grammar of man page a bit
-  add some ranges to the man page to indicate what values are valid

Since fwcontrol's code is the same across 6/7/head this can be
applied to all branches after the MFC period.
