Subject: veth: Do a better job cleaning up on rmmod
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b9f9f37fb7a85dbe58a260f6e1b745a17db66dd5;p=openvswitch

veth: Do a better job cleaning up on rmmod

The veth driver doesn't clean itself up very well when removed.  This
commit destroys any outstanding veth devices and then unregisters its
sysfs entry.
