From 8e52533d109571915a0006533e2e1adb01face00 Mon Sep 17 00:00:00 2001 From: Andrew Ruder Date: Tue, 22 Oct 2013 19:10:28 -0500 Subject: [PATCH] net: tftpsrv: Get correct client MAC address 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.
