X-BeenThere: edk2-devel@lists.01.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: EDK II Development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Ruiyu Ni , Ye Ting , Fu Siyuan , 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" After HTTP boot successfully in home mode, the HTTP device path will be updated accordingly. So, the new device path may be appended with a DNS device path node. When executing home mode boot again, the original HTTP device path will mismatch with the new updated one, which will cause the HTTP boot failure. So, we need update the current match algorithm to match the correct FilePath. Since the DNS device path is an optional, we can skip it check. This patch is to fix above issue.
