Subject: learn: Initialize cookie_mask in constructed flow_mod.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9ed20b8a36555a39e3cda9900c6adc0e2f5ae2c2;p=openvswitch

learn: Initialize cookie_mask in constructed flow_mod.

Otherwise the "learn" action may not correctly set the cookie in flows that
it creates.

Found by valgrind.
