Subject: Re: kern/29660: vlans broken on bge(4)

 [strangely I didn't receive Manuel's comment via email, but by checking
 the gnats database.. Shouldn't it be sent on automatically?]
 
 Anyway, bge(4) knows about vlans, so it doesn't have the "can't cope with
 the extra 4 bytes so reduce mtu" problem. Both bge and vlan interfaces
 are set to 1500.
 
 Doing the above test on the same machine with a 3com 3c905cx-tx-m gets
 4.6MB/s in both configurations, ie, it doesn't matter whether or not we
 are tagging.
 
 Funnily enough, I get the same result (4.6MB/s in both cases) for an old
 realtek card on an ancient laptop. rtk doesn't understand vlans, so the
 vlan interface has a lower mtu, but this didn't make the interface noticably
 slower in my primitive test. We aren't talking fractions of second here!
