Subject: VLAN packets silently dropped in promiscuous mode
Date: Wed, 29 Sep 2010 13:37:57 +0200 [thread overview]
Message-ID: <20100929113757.GA23755@core.hellgate.ch> (raw)
I noticed packets for unknown VLANs getting silently dropped even in
promiscuous mode (this is true only for the hardware accelerated path).
netif_nit_deliver was introduced specifically to prevent that, but the
function gets called only _after_ packets from unknown VLANs have been
dropped.
Presumably this has been the case since

vlan: Add GRO interfaces
I didn't find any indication that the change in behavior is intentional. Is
it?
