From 9ace17c88ae8bd5f29fb44849f6855b8bd456869 Mon Sep 17 00:00:00 2001 From: Ilya Yanok Date: Mon, 17 Sep 2012 10:26:25 +0000 Subject: [PATCH] net/bootp: add VCI support for BOOTP also Vendor Class Identifier option is common to BOOTP and DHCP and can be useful without PXE. So send VCI in both BOOTP and DHCP requests if CONFIG_BOOTP_VCI_STRING is defined.
