X-BeenThere: edk2-devel@lists.01.org X-Mailman-Version: 2.1.22 Precedence: list List-Id: EDK II Development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Ye Ting , Wu Jiaxin MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable Errors-To: edk2-devel-bounces@lists.01.org Sender: "edk2-devel" X-ZohoMail: RSF_4 Z_629925259 SPT_0 Content-Type: text/plain; charset="utf-8" The IP driver uses EfiCreateProtocolNotifyEvent() to register notify callba= ck function for IpSec protocol, but it didn't notice that the callback will al= ways be executed at least once, even the protocol wasn't in handle database. As a result, the Ip4IpSecProcessPacket() will still always call LocateProto= col() even the IpSec protocol is not installed, which will impact the network performance.
