Subject: app-layer: method to see if parser supports tx detect flags
X-Git-Tag: suricata-5.0.1~76
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=739df21e2d87fe195a09334f66409f458711f3f8;p=thirdparty%2Fsuricata.git

app-layer: method to see if parser supports tx detect flags

Add method to check if a parser for an app-layer protocol
supports tx detect flags.

This is a bit of a hack for now as where we need to run
this check from we do not have the IP protocol.
