Subject: ovs-vsctl: Use vsctl_fatal() consistently.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=def90f6204f7cab8a23f5352c2be26b7cf8586f5;p=openvswitch

ovs-vsctl: Use vsctl_fatal() consistently.

vsctl_fatal() logs its argument as well as printing it on stderr, so it
is preferable within ovs-vsctl.  An upcoming commit will also make
vsctl_fatal() free memory, so using it consistently will also make that
memory freed consistently.
