From ccc9d946e39a3d9841296662656df2c697f23689 Mon Sep 17 00:00:00 2001 From: Yi Zhao Date: Tue, 25 May 2021 16:56:15 +0800 Subject: [PATCH] dhcp-relay: add recipe The current default dhcp server kea in oe-core doesn't provide dhcp-relay tool. Add a recipe to provide dhcrelay which is from dhcp. This patch is picked up from dhcp recipe with some tweaks. In order to fix the build dependency, we use bundled bind instead of external bind.
