Subject: [PATCH net-next 3/4] net: microchip: vcap: Add vcap_rule_get_key_u32
Date: Wed, 30 Nov 2022 15:35:24 +0100 [thread overview]
Message-ID: <20221130143525.934906-4-horatiu.vultur@microchip.com> (raw)
In-Reply-To: <20221130143525.934906-1-horatiu.vultur@microchip.com>
Add the function vcap_rule_get_key_u32 which allows to get the value and
the mask of a key that exist on the rule. If the key doesn't exist,
it would return error.
