Subject: When a new OpenFlow kernel module package is installed, restart the switch.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0e061502c94f262adf2932c75ac40e2312438300;p=openvswitch

When a new OpenFlow kernel module package is installed, restart the switch.

This helps to ensure that the secchan and the kernel module are exactly
the same version.
