Put another way, once you enable VLAN header stripping, you won't see the headers for *any* VLAN, not only for those you're actually running locally. This is also a problem for devices like macvlan, where it would be desirable to make use of hardware VLAN accerlation. I was thinking about storing the information somewhere in the packets meta-data on both RX and TX paths, that would also allow tcpdump to properly display packets. I have planned to look into this when I find some time. Your suggestion of disabling VLAN acceleration in promiscous mode sounds like a reasonable solution until then .. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
