From 30268f29bd38a8e07b9914a1be00583c172c4c40 Mon Sep 17 00:00:00 2001 From: Fu Siyuan Date: Fri, 16 Oct 2015 07:18:38 +0000 Subject: [PATCH] MdeModulePkg: reset DHCP child when leaving PXE LoadFile. The DHCP4 can have only one configured child instance so we need to reset the DHCP4 child when leaving PXE driver's LoadFile() function, otherwise the other programs which also need to use DHCP4 (like HTTP boot) will be impacted.
