From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrew Ruder Date: Tue, 22 Oct 2013 19:10:28 -0500 Subject: [U-Boot] [PATCH] net: tftpsrv: Get correct client MAC address Message-ID: <20131023001028.GA2118@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de NetServerEther was not being cleared in the tftp server code, so the destination MAC address would be whatever the last destination MAC address was. Scenario: U-Boot: dhcp tftpsrv Host: Send device WRQ Device: Responds with ACK to dhcp server mac address with host ip address By clearing NetServerEther, we force a lookup of the host MAC address to go with the associated host IP.
