Subject: Give Suricata priority to receive packets over Linux with mPIPE.
X-Git-Tag: suricata-2.0beta2~170
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=86c6861b402bbd8ddc841bd86531fab85efc7e47;p=thirdparty%2Fsuricata.git

Give Suricata priority to receive packets over Linux with mPIPE.

When installing the rules to tell mPIPE to send packet to Suricata,
give it a higher priority than the default used by Linux. This way if
Linux also tells mPIPE to send it packets, Suricata will get them
instead, as long as Suricata is running.
