Subject: [PATCH net-next 1/5] net: mvpp2: cls: Use the correct number of rules in various places
Date: Fri, 24 May 2019 12:05:50 +0200 [thread overview]
Message-ID: <20190524100554.8606-2-maxime.chevallier@bootlin.com> (raw)
In-Reply-To: <20190524100554.8606-1-maxime.chevallier@bootlin.com>
As of today, the classification offload implementation only supports 4
different rules to be offloaded. This number has been hardcoded in the
rule insertion function, and the wrong define is being used elsewhere.
Use the correct #define everywhere to make sure we always check for the
correct number of rules.
