Subject: ofp-parse: ofp-parse fails to properly validate DROP.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d13803eb5a5af97a5b35193ce5887c4e4cb10e8a;p=openvswitch

ofp-parse: ofp-parse fails to properly validate DROP.

The str_to_action function of ofp-parse was not properly
incrementing it's actions counter.  Thus it did not enforce the
requirement that DROP actions not be preceded by other actions.
