Comment 1 for bug 2051351

@Bence,

``explicity_egress_direct`` was mainly added for openvswitch firewall driver. Noop firewall driver is not the primary case of this option. There is a bug which is related to iptables_hybird drivers, so the fix is added to noop and iptables_hybird drivers as well.

But anyway, TBH, this option is not really cover the trunk port scenario. If trunk port is widely used, it's worthy to have a fix to cover it.

So this bug is mainly for trunk port scenario?

So, we are facing more cases as I said before:
