From 5cb014f1431ff1849062804afb9b9658ca588fca Mon Sep 17 00:00:00 2001 From: Manuel Buil Date: Tue, 21 Mar 2017 16:08:13 +0100 Subject: Bug fix: Eth header build with wrong dest. mac JIRA: SFC-89 The second test fetches the destination mac of the previous test because an entry with that IP is in the arp table. However, that table is outdated. We must flush the arp table before starting the new test.
