From 630113e74872d47d54d6b6234a864514d582193c Mon Sep 17 00:00:00 2001 From: zsdc Date: Wed, 21 Aug 2024 21:55:17 +0300 Subject: dhclient: T6667: Added workaround for communication with FRR To increase the chance for dhclient to configure routes in FRR, added a workaround. Now 10 attempts are performed with 1 second delay and only after this dhclient gives up.
