From fe32dffdcd33d34bc9bab267a55a8726074b0010 Mon Sep 17 00:00:00 2001 From: Joachim Wiberg Date: Fri, 22 Apr 2022 13:14:58 +0300 Subject: selftests: forwarding: add TCPDUMP_EXTRA_FLAGS to lib.sh For some use-cases we may want to change the tcpdump flags used in tcpdump_start(). For instance, observing interfaces without the PROMISC flag, e.g. to see what's really being forwarded to the bridge interface.
