Subject: unixctl: Improve error reporting.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a723bf84fb639262d2bf7e33b7640a9621bb19b5;p=openvswitch

unixctl: Improve error reporting.

The ovs_error() function is our standard way of reporting startup errors,
so use it.  (It also outputs the program name at the beginning of the
message.)
